What to do when you receive an ADA Compliance letter?

Over the last few years, many businesses have received letters from attorneys advising them that their website is not ADA compliant. 

If you receive one of these letters, make sure that those reaching out to you include a REPORT showing: 

  • Which tool they used to audit your website on?
  • What score your website received as well as recommendations on what to fix in order to get your site a higher score?
    (Without a report, there is no way to know what they found and what they are requiring to make your website compliant.)

There are three levels for WCAG 2.1 Guidelines and each one meets the needs of different groups and different situations:

A – lowest with 25 criteria your website must reach
AA – mid range – in addition to the level A criteria, your website needs to meet 13 more criteria
AAA – highest – all of A and AA plus an additional 23 criteria that your site needs to meet

The standard recommended level of compliance, and the level most often legally required for websites, is AA. The AAA level is required for government and banking institutions. As web developers, we aim to get our clients to 90+ at the AA level using Google’s Lighthouse Tool which covers many WCAG 2.1 Level AA requirements.
https://www.boia.org/blog/googles-lighthouse-accessibility-tests-are-helpful-but-not-perfect ]

Asking to have your website 100% ADA compliant is not reasonable and is almost impossible to ensure because:

1. There are many tools out there to run website audits on, and each one ranks websites differently depending on the parameters their tool is set at because it’s not a “pass-fail” test.

2. Which browser are they running the audit on ( Chrome, Firefox, Safari, etc.) effects the score 

3. There are endless variations in the type and severity of disabilities.
https://myaccessible.website/blog/wcaglevels/wcag-levels-a-aa-aaa-difference ]

The WCAG Guidelines are centered around these 4 main principles:

Principle 1 – Perceivable: Information and user interface components must be presentable to users in ways they can perceive
Using one or more of their senses, users need to be able to perceive and understand your website in some significant way.

Principle 2 – Operable : User interface components and navigation must be operable
Users need to have the ability to navigate through your website and UI elements like the ability to click a button either with a mouse, voice command, or other method

Principle 3 – Understandable: Information and the operation of the user interface must be understandable
Your website content should be readable, understandable and digestible to readers.

Principle 4 – Robust : Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies
Your website’s content needs to be developed keeping in mind how it will work across different types of browsers, both presently and in looking ahead to the future.

Add WP Bootstrap Navwalker To You WordPress Theme

Why Add Bootstrap Navwalker?

The main reason for adding this addition to your WordPress Theme is best said by its author [Git Link]

A custom WordPress Nav Walker Class to fully implement the Bootstrap 4 navigation style in a custom theme using the WordPress built in menu manager.”

By implementing this code, you will be changing how the menus are generated by WordPress. This will allow the incorporation of Bootstrap 4 styling and standards found on a pure Bootstrap built website. This addition should be pair with an installation of Bootstrap by Twitter [Link] and a consideration for using a Bootstrap focused design.

Please check out “ADDING BOOTSTRAP TO AN UNDERSCORES THEME”  for a detailed guide demonstrating how to add and create a brand new underscores theme with a bootstrap integration.

Downloading the Navwalker Files

Lets head over to the main Git Repo for WP Bootstrap Navwalker [Link]. Go ahead and download a copy of repository and open the downloaded Zip file.

Open the downloaded Zip and select the file called:


Place this file in your active theme folder, or the theme folder you plan to use. File Path should look like so:

Main website folder (folder) -> wp-content (folder) -> themes (folder) -> theme folder (folder) -> add class-wp-bootstrap-navwalker.php

Integration of WP Navwalker

Now that your file has been added to your theme we can start hooking up the Navwalker to your Menus, First lets head over to the functions.php file located in the theme folder – and add the following code:

 * Register Custom Navigation Walker
function register_navwalker(){
	require_once get_template_directory() . '/class-wp-bootstrap-navwalker.php';
add_action( 'after_setup_theme', 'register_navwalker' );

If you encounter errors with the above code use a check like this to return clean errors to help diagnose the problem.

if ( ! file_exists( get_template_directory() . '/class-wp-bootstrap-navwalker.php' ) ) {
    // File does not exist... return an error.
    return new WP_Error( 'class-wp-bootstrap-navwalker-missing', __( 'It appears the class-wp-bootstrap-navwalker.php file may be missing.', 'wp-bootstrap-navwalker' ) );
} else {
    // File exists... require it.
    require_once get_template_directory() . '/class-wp-bootstrap-navwalker.php';

If no menu has been previously declared, please declare a new menu in your functions.php file.

register_nav_menus( array(
    'primary' => __( 'Primary Menu', 'THEMENAME' ),
) );

Using WP Navwalker in your menu

Lets take a second to look at what we have completed. First, we added the files needed to use WP Navwalker with our theme, added the code necessary to connect the new WP Navwalker file to our WordPress Theme, and for our last step we will create a Menu (most likely located in the header.php file) that will use WP Navwalker!

To update any Wordpress Menu in your theme with the newly added Navwalker use the new wp_nav_menu argument by adding a ‘walker’ item to the wp_nav_menu args array.

wp_nav_menu( array(
    'theme_location'  => 'primary',
    'depth'           => 2, // 1 = no dropdowns, 2 = with dropdowns.
    'container'       => 'div',
    'container_class' => 'collapse navbar-collapse',
    'container_id'    => 'bs-example-navbar-collapse-1',
    'menu_class'      => 'navbar-nav mr-auto',
    'fallback_cb'     => 'WP_Bootstrap_Navwalker::fallback',
    'walker'          => new WP_Bootstrap_Navwalker(),
) );

You menu will now implement the same drop down features found in the Bootstrap by Twitter examples!

Typically additional markup is added to these menus, here is an example of a fixed-top menu that collapse for responsive navigation at the md breakpoint. Additional menu options can also be found in the Bootstrap documentation as well [Link]

<nav class="navbar navbar-expand-md navbar-light bg-light" role="navigation">
  <div class="container">
    <!-- Brand and toggle get grouped for better mobile display -->
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-controls="bs-example-navbar-collapse-1" aria-expanded="false" aria-label="<?php esc_attr_e( 'Toggle navigation', 'your-theme-slug' ); ?>">
        <span class="navbar-toggler-icon"></span>
    <a class="navbar-brand" href="#">Navbar</a>
        wp_nav_menu( array(
            'theme_location'    => 'primary',
            'depth'             => 2,
            'container'         => 'div',
            'container_class'   => 'collapse navbar-collapse',
            'container_id'      => 'bs-example-navbar-collapse-1',
            'menu_class'        => 'nav navbar-nav',
            'fallback_cb'       => 'WP_Bootstrap_Navwalker::fallback',
            'walker'            => new WP_Bootstrap_Navwalker(),
        ) );

To change your menu style add Bootstrap nav class names to the menu_class declaration.

Review options in the Bootstrap docs for more information on nav classes.

You should now have a fully functioning Bootstrap by Twitter Drop down menu integrating into you WordPress theme!

Adding Bootstrap to an UnderScores Theme

In this article, we will be discussing how to add Bootstrap by Twitter to an Underscores.me WordPress Theme! There is much to be desired from this simple combination, and for most it is a great place to start for creating you own custom WordPress Theme. This article will expect that you understand the folder and file structure of a WordPress site, as well as the multiple different hooks and functions found in a WordPress Theme’s function.php file.

Add Underscores Theme Template

First we will need to download our theme template by going to Underscores.me and generating the base theme. Feel free to name your theme during this step as well!

home page of underscores.me

Now that your Underscores Theme is downloaded, head over to the backend of your WordPress website. Once logged in, go to “Appearance” -> “Themes”, click the “Add New” button and then the “Upload Theme” button located around the top of the page. Select the previously downloaded .zip file from Underscores and click “Install Now”. All that should be left is to “Activate” your new blank and almost formate-less theme.

Theme section of a WordPress webstie

Download & Add Bootstrap

Now that we have your Underscores.me theme added and activated, its time to download and add our Bootstrap files! Go to getBootstrap.com click on the “Download” button located at the top right of the page, then download the files under the section titles “Compiled CSS and JS”.

download Bootstrap

open the downloaded .zip file “bootstrap-{version #}-dist.zip”, and rename the extracted folder to “bootstrap”. placed the newly renamed folder inside of your newly added underscores theme folder. This will be located: WordPress (Root Folder) -> wp-content (folder) -> themes (folder) -> {underscores theme name} (folder) – place the “bootstrap” (folder) here.

File Order

Connecting Bootstrap to Underscores Theme

Now that Bootstrap is located inside of your Underscore.me Theme, its time to hook them together. Open your function.php file located in your Underscores.me Theme folder. Add the following code in the to the style enqueuing function located around line:145

// Adding Bootstrap to the Theme - Start

wp_enqueue_style( 'bootstrap-style', get_template_directory_uri() . '/bootstrap/css/bootstrap.min.css' );
wp_enqueue_script( 'bootstrap-js' , get_template_directory_uri() . '/bootstrap/js/bootstrap.bundle.min.js', array('jquery') );

// Adding Bootstrap to the Theme - Start

Example of a completed function.php file:

Save the function.php and you are all done! Now all that is left is to enjoy creating a custom WordPress theme!

Disable Comments on Media

Comments can be a great way to interact with your Users and add some personality to your website by including your them in the conversation. However, you may not need the comments section for all features on your site.

In this article we will be focusing on how to remove the comment section from WordPress “Media” content

Where Are We Disabling Comments…?

The specific place we will be removing comments can be found through the following steps:

  1. Log into the backend of you WordPress Website
  2. Go to the “Media Library”
  3. Click on one of the media sources located in the “Media Library”
  4. Open the link titled “View attachment page”

steps 2-3

step 4

How To Disable Comments on Media

Go to the functions.php file located in the Theme folder of your WordPress website.

Add the following code to the bottom the the functions.php file:

function filter_media_comment_status( $open, $post_id ) {
$post = get_post( $post_id );
if( $post->post_type == 'attachment' ) {
return false;
return $open;
add_filter( 'comments_open', 'filter_media_comment_status', 10 , 2 );

Now sit back and relax knowing no one will be commenting on your Media anymore!

How To Increase Maximum File Upload Size in WordPress

Are you looking to increase the maximum file size you’re able to upload to your WordPress Site? Sometimes the default settings might not be enough to handle the uploads you are looking to make. Whether you’re looking to upload larger images, new plugins, or large theme files, having control over the size limit is an important skill to have. Now let’s dive into how to increase the maximum file upload size in WordPress.

***This is a intermediate skill and REQUIRES some WordPress, File Structure, and FTP Access***

These solutions may also not work with some shared host, however contacting you hosting service provider for support should solve your problem. Also, these are solutions that have been found successful in a number of unique situations, however do note that these solutions do not account for all possible situations.

First Let’s Check Your CURRENT Max File Upload Size

WordPress will automatically show you the current maximum file limit in the “”Media” area of you Admin Dashboard. To find the maximum upload file size go to Admin Dashboard >> Media >> Add New.

1. Editing the Theme Functions File

In some instance all you need to do is copy and paste the following code to your functions.php file. If you want a different size limit, Change ’64M’ to the appropriate amount, example: ‘128M’ . You can get to this file by: Admin Dashboard >> Appearance >> Theme Editor >> Select File “Functions.php”

@ini_set( 'upload_max_size' , '64M' );
@ini_set( 'post_max_size', '64M');
@ini_set( 'max_execution_time', '300' );

Through ini_set(); we can access our PHP configurations and re-write them to suit our needs

2. Creating / Editing a php.ini File

For this next method you will need to have access to your website’s root folder, whether it be through FTP or some other File Managment App

When in your root folder look for a file called “php.ini” this is a configuration file for your site. If you Do NOT see a “php.ini” file please create a blank file called “php.ini”. Once inside this file, whether the file is brand new or old, add the following code to it.

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

Now that the code is in your file, save and check your site. If you are adding this code to an existing php.ini file search through the file, should be fairly small, and make sure that the code you have copy and pasted into this file is not located any where else. If so delete the code with the incorrect values.

3. Editing the .htaccess File

This last and final method involves editing the .htaccess file that is found in the root folder of your website.

Open the file and copy and paste the following code:

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300

Again it is important to note that these methods have worked well for a lot of different websites in a lot different situation, however the 3 methods above can not account for all possible development environments. If you are on a shared hosting package I highly suggest contacting your web hosting provider and discuss increasing the limit for you first.

Hope this article has helped you along your way and has improved your site!

What is a Hard Refresh and How to do it

What is a Hard Refresh?

Hard Refresh is a way of clearing out the browser’s (i.e. Chrome, Firefox, Safari, etc.) cache for a specific page. Clearing the cache will force your browser to load the most recent version of the files used for a specific page, this usually include stylesheets or other important scripts. Clearing of a browser’s cache should be completed every time an update is made on a site, this will allow a view to always see the intended files associated with any and all updates.

Clicking the refresh button located near the address bar IS NOT the same as a hard refresh

How to Hard Refresh in Google Chrome Chrome Logo

Make sure you are on the web page you would like too hard refresh.

  • Windows: hold down Ctrl and then press F5 on your keyboard
  • MAC: hold down ⌘ Cmd and ⇧ Shift and then press R on your keyboard

How to Hard Refresh in Firefox Firefox Logo

Make sure you are on the web page you would like too hard refresh.

  • Windows: hold down Ctrl and then press F5 on your keyboard
  • MAC: hold down ⌘ Cmd and ⇧ Shift and then press R on your keyboard

How to Hard Refresh in Safari Safari Logo

Make sure you are on the web page you would like too hard refresh on a MAC computer.

  • Step #1: Go to Safari (Top right corner of screen near Apple logo) → Preferences → Advanced → (Check Box) Show Develop menu in menu bar
  • Step #2: Go to Develop (Top right corner of screen near Apple logo and left of Safari) → Empty Caches


Create Your First Google reCaptcha Keys

Why Do I Need a reCAPTCHA?

According to Google:

reCAPTCHA is a free service from Google that helps protect websites from spam and abuse. A “CAPTCHA” is a turing test to tell human and bots apart. It is easy for humans to solve, but hard for “bots” and other malicious software to figure out.


Basically adding a reCAPTCHA will help reduce the amount of SPAM / BOTS trying to submit or add to your site.

However, You are here in order to learn how to CREATE a Google reCAPTCHA. So let’s get started

Log Into Your Google Acct. & Search

search for google recaptcha

  • Make sure you are signed into your, or your company’s, google
  • Search for “google recaptcha admin” at google.com

Google reCAPTCHA Admin

  • Look for the Google reCAPTCHA link in your google search results

The Form

below is a blank version of the form that you will be directed to.

Filling Out The Form

STEP #1 (Label)

  • This section is purely for your reference, I suggest using your Domain name and some descriptor
    • Example: dhali.com – reCAPTCHA

Step #2 (reCAPTCHA type)

  • Select the version of reCAPTCHA you would like to use **Which reCAPTCHA you pick is determined by the service you are using**
    • The example above is specifically for the reCAPTCHA Check Box as seen below.
    • This reCAPTCHA check is what you will want to use if you are using the Gravity Forms Plugin by RocketGenius
  • To get reCAPTCHA check box
    • Select: reCAPTCHA v2
      • Select: “I’m not a robot” Checkbox

Step #3 (Domains)

  • In this section you will be letting Google know which website you want this reCAPTCHA to work on.
  • In the text field simply but your website Domain Name.
  • If you copy your website’s url you might see something like this
    • https://www.dhali.com
  • The part that you want to type into this section is just the Domain, for example:
    • dhali.com
    • NO http// or https//, NO www.
  • If you have additional Domain names you’d like to add simply click the “+” and add another using the same logic.

Step #4 (Owners)

In this section you will see the email address associated with the current Google Account you are using is already present. If you would like to allow another Google Account access to this reCAPTCHA settings page you will add their email here.

Step #5 (Accept the Terms & Email Notifications)

  • Read Terms and Conditions
    • Check the box – Accepting Terms of Service
  • If you would like Google to notify you about suspicious activity on the form where your reCAPTCHA located check the box
    • Send Alerts to Owners
  • Everything should now be filled out!
    • click “Submit”

Copy & Save reCAPTCHA Keys

Above is the Site Key and the Site Secret Key for your new Google reCAPTCHA! Copy these keys and add them to your Plugin or Favorite Developer!

  • Around the middle top of the page click “+ CREATE CREDENTIALS”
  • Then Click “API Key”

Copy Your New API Key

  • Simply copy the the Key and you are all done.
  • Speak with your IT Professional about the appropriate ways to keep your API key secure.

Advance Custom Field PRO Repeaters

Advance custom fields is a very powerful plugin for WordPress. In this blog post I will be teaching you how to use the Repeater field from Advance Custom Fields PRO. There are will be two steps that are required to get the Repeater working.

WordPress Admin

Log into the your site back in and make sure you have administrator privileges. If you do not have Advance Custom Fields PRO installed and the license activated please take time to do this.

Steps for creating the Repeater Field:

  • On the left hand side of your Dashboard there should be “Custom Fields”
  • This is where all the Field Groups are that you have created for your site. Press “Add New” on the top of the page
  • The first entry field is the title of the ACF. This will only be seen on the back end when a user is trying to add data. This can be whatever you want. For this demo I will be calling mine “Repeater Test”.
  • Next what you want to do is press the blue button that says “+ Add Field”. This is where we are going to create our repeater field.
    • Field Label: This is the title of the repeating element. For example: If you want a page to have multiple Icons, the Field Label will be “Icons”, If you want different display blocks the Field Label will be “Blocks”, etc.
    • Field Name: This is automatically generated when you add the first Field Label. This will be used when we are writing the Code. Make sure there are no spaces in this field. The best practice is to add a Field Label and use the auto generated name.
    • Field Type: For this example we are using Repeater. Note: If you do not have the PRO version there will be no Repeater for you to select.
    • Instructions: Displays to user on back end to explain how to add data
    • Required: If you want it to be required.
    • Sub Fields: These are the items that you want to be repeated. Press “+ Add Field”.
      • I will not be going over all of the options today. Just make sure you add a Field Label and Field Name so we can access the data in the code.
      • For my example I will be adding an Image (Image), Title (Text), and Description (Text).
      • *Note: For the Image there is an option called Return Value. My code will be handling “Image Array”.
    • The rest of the VALUES can be changed as you feel fit! This is all we need for my code.
  • Make sure you press “Publish” on the top to complete the process

Steps for adding Data:

  • If you chose to display the form on Post or Pages navigate to the correct Post or Page you wish for the data to be entered
  • Click “Add Row” and enter in the data.
  • Keep pressing “Add Row” until all the data is entered.
  • You can delete a row on the left hand column.
  • Or reorder the row by dragging the numbers on the left hand column

PHP Code

This part of the process it going to be more difficult. This will required previous knowledge on the PHP side of WordPress. I will no go over the process of finding the correct location to add the code but these are my recommendations. Either create a Page-current page if that is were the ACF is. Or Add a template part for the posts.

Improving Website Page Speed Performance

Page Speed on a website can help especially for mobile users visiting your website. We recommend testing a website across different tools and not just relying on one.  Some of the tools we use for testing Page Speed performance are WebPageTest.org, Pingdom Website Speed Test, and Google PageSpeed Insights.

Image Optimazation

This is often overlooked but it’s probably the most important aspect of optimizing your website. Some methods/tools of image optimization you can use are

  • Photoshop – You can export images and save them at Quality 70
  • TinyPng.com – Allows you to upload both .jpg, .png files 20 at a time and optimizes them for you.
  • Grunt – Running a task to optimize your images while developing. We use grunt-contrib-imagemin.

Minify/Concat JS/CSS files

If you have multiple js/css resources on your site concatinating and minifying these files into 1 single file will help improve Page Speed performance. A Grunt Task can also help with this task. grunt-contrib-cssmin and grunt-contrib-uglify. Below is an example of what a Gruntfile.js may look like when using grunt-contrib-cssmin and grunt-contrib-uglify.

uglify: {
  options: {
    mangle: false,
    sourceMap: true
  my_target: {
    files: {
      'assets/js/scripts.min.js': [
cssmin: {
  options: {
    sourceMap: true
  target: {
    files: {
      'assets/css/styles.min.css': [

WordPress vs Squarespace

At Dhali we design most of our sites using WordPress. WordPress is a powerful open source software and tool for building websites and apps. Some estimate that over 25% of ALL websites are currently built with WordPress.

The most common use for a WordPress site is as a content management system, or CMS. This allows users to edit their website like a Google Doc. Along with the intuitive CMS, WordPress has a multitude of powerful tools “under the hood”. These tools allow our development team to make beautiful, easy to edit websites.

Another popular CMS is the new kid on the block, Squarespace. Squarespace is a beautiful, although limited, alternative to WordPress. Squarespace thrives off of its “drag and drop” system and pre-made themes. These tools allow users to create professional looking sites with no code or prior experience.

So which is best for you, WordPress or Squarespace?

The answer is it depends.

To decide, you must have the goal of the website in mind. The best way to explain this is by giving a few examples. As you will see, the choice almost always boils down to functionality and flexibility.


Let’s say you are a photographer who needs a simple portfolio site. The goal of the site is to showcase your work and set up a contact form for potential clients to reach you. You don’t have a large budget want to get started immediately.

The immediate answer here is Squarespace.

Why? Squarespace has a few pre-built templates for portfolios to get you started. Because you have a small budget, the upfront cost will only be for your domain name and first month of Squarespace. If you spend a few hours uploading your photos and connecting an email address, your site is as good as live.

Why you shouldn’t choose Squarespace.
Let’s say down the line you want to add in some sort of social interaction to your site, such as the ability to “like” photos. Squarespace simply does not have this functionality. Also, because Squarespace severs are the only place you can host Squarespace sites, you will never be able to transfer your website to another hosting provider.

Small Business

Let’s say that you are a small business looking to grow their online presence. The goal of your website is to display your products and reach out to potential clients. Your brand has a very distinct style, and in the future you hope to add eCommerce to your site so that you may sell products online.

The answer here is WordPress.

Building this site on WordPress will allow you to start with the end in mind. Phase one of the project will be getting the website up and running and adding in various pages and products. Phase two can then be implemented down the road, giving your site the eCommerce functionality when you need it.

In addition, with WordPress where you host your site is completely up to you, allowing further flexibility. All while branding and customizing your site to look the way you want it.

That’s where we come in.

Our team at Dhali has the skills and tools available to help you achieve your goals. We design fully customized sites with the future in mind, and even show you show to add to your WordPress website.

(We also offer hosting programs that cover everything from security maintenance to posting blogs)

See for your self!

Update Your WordPress Website

Clients often ask what the benefits are of updating their WordPress site, including plugins and themes. While some of the benefits include fixing/addressing bugs, adding key features and increased functionality, the main reason why it is vital to be on top of your WordPress site maintenance is security reasons.

According to WPBeginner, more than 80% of WordPress sites that had not been properly maintained and updated were hacked.

There are different reasons as to why WordPress sites are frequently hacked. Most of hacks, however, can be traced back to the fact that the site is running on outdated versions of PHP, WordPress, themes, or plugins. By not updating your WordPress site regularly and in conjunction with the released WordPress updates, you are leaving your website buggy and unprotected to hacks.

We have a tested and true process for maintaining all client WordPress Websites:

  1. Read the release notes or changelog to see what the updates change.
  2. Test the update on a development site. That way, if anything breaks, we can troubleshoot before updating your live site.
  3. Back up your site.
  4. Install the updates.
  5. Review and test your site. Focus on the items that were noted in the release notes or changelog.

Just like you need to install an update on your operating system for your mobile phone, web applications such as WordPress need the same software updates from time to time.
