How to Install the WebAbility Accessibility Enhancer on WordPress
Before You Begin
Installing WebAbility on WordPress is straightforward, whether you're using our dedicated plugin or adding the Accessibility Enhancer code directly. Let's get your WordPress site accessible in minutes.
What you'll need:
- Admin access to your WordPress dashboard
- Your WebAbility account credentials
- 5-10 minutes (depending on your method)
Compatibility:
WebAbility works seamlessly with:
- WordPress 5.0+ (we recommend 6.0+ for best performance)
- All major page builders (Elementor, Divi, Beaver Builder, WPBakery)
- WooCommerce and other e-commerce plugins
- Multisite installations
- Custom themes and child themes
- Popular caching plugins (we'll show you how to configure them)
Why WordPress Sites Need Accessibility
WordPress powers 43% of the web, but most WordPress sites have significant accessibility gaps. Here's what you need to know:
The WordPress Accessibility Challenge:
- Theme developers often prioritize aesthetics over accessibility
- Plugins can introduce accessibility barriers
- Page builders may generate non-semantic HTML
- Custom CSS can break keyboard navigation
- Media libraries often lack proper alt text management
Legal & Business Impact:
- WordPress sites are frequently targeted in ADA lawsuits
- Government contractors must meet Section 508 requirements
- Educational institutions need WCAG 2.1 AA compliance
- Better accessibility means better SEO (Google rewards accessible sites)
Common WordPress Issues WebAbility Fixes:
- Missing form labels in Contact Form 7, WPForms, Gravity Forms
- Inaccessible WooCommerce checkout processes
- Slider plugins that can't be keyboard controlled
- Pop-up plugins that trap screen readers
- Menu systems without proper ARIA labels
Installation Method 1: WordPress Plugin (Easiest)
Step 1: Sign Up for WebAbility
- Sign up for Webability. If you already have an account, select Log in.
- Click Add site and enter your domain. A new site starts a 30-day free trial. No card is needed.
Step 2: Install the Plugin
- In your WordPress dashboard, go to Plugins → Add Plugins
- Search for WebAbility Accessibility Widget or install it directly from the WordPress plugin repository
- Select Install Now. Once it's installed, the Install Now button will change to Activate.
- Select Activate
Step 3: Configure the Accessibility Enhancer
- Go to Settings → WebAbility to configure the Accessibility Enhancer
- Enable the Accessibility Enhancer and customize the position to your preference
- Use the verify button to ensure your domain is properly configured
Step 4: LiteSpeed Cache (only if you use it) If your site uses LiteSpeed Cache (common on LiteSpeed hosting), add this pattern on its own line under LiteSpeed Cache → Cache → Private Cached URIs so the Accessibility Enhancer is not cached as public HTML and keeps working for every visitor:
^/widget-v2\.webability\.io/
Save your LiteSpeed Cache settings at the top or bottom of that screen. See the screenshot below for where to paste it.
That's it! The Accessibility Enhancer will now appear on your site. Clear your cache if you don't see it immediately.
Alternative Installation Methods
Recommended: Use the WordPress plugin method described above for the easiest installation. The methods below are for advanced users or special use cases.
Getting Your Installation Snippet
- On the WebAbility homepage, click Login in the top right corner, and log in to your account.
- Go to Sites in the left menu and select your site.
- Settings > Installation - Install the WebAbility Accessibility Enhancer with our default settings and design to provide the best customer experience.
Quick installation
For best results, paste the installation code right before the ending of the body tag on your website.
<script src="https://enhancer.webability.io/widget.min.js" data-asw-position="bottom-left-x-20-y-20" data-asw-lang="auto" data-asw-icon-type="m-full" defer></script>This is an example. Copy your own snippet from your WebAbility dashboard: Sites, select your site, Settings tab, Installation. It has your position, language and icon settings.
- Copy your own installation script from your WebAbility dashboard: Sites, select your site, Settings tab, Installation.
- Now that you have your installation script you can add it to WordPress.
Advanced: Using JavaScript Plugins
For those who prefer using a JavaScript management plugin:
Recommended Plugins:
- WPCode – previously known as Insert Headers and Footers
- Simple Custom CSS and JS
- Header Footer Code Management
These plugins provide an easy interface to manage JavaScript snippets and allow conditional loading rules.
Installation Method 2: Manual Code Installation
For Advanced Users: If you prefer manual installation or the plugin doesn't suit your needs:
Option A: Via Theme Functions Add to your theme's functions.php or custom plugin:
function add_webability_widget() {
if (!is_admin()) {
echo '<script src="https://enhancer.webability.io/widget.min.js" async></script>';
}
}
add_action('wp_footer', 'add_webability_widget');
Option B: Via Header/Footer Plugin
- Install a plugin like "Insert Headers and Footers"
- Add the WebAbility script to the footer section
- Save and test
Option C: Direct Theme Edit
- Go to Appearance → Theme Editor
- Select footer.php
- Add the script before the closing </body> tag
- Update file
Post-Installation Setup
Cache Configuration: If using caching plugins, add these exclusions:
- WP Rocket: Exclude /enhancer.webability.io/ from minification
- W3 Total Cache: Add widget.min.js to "Never minify" list
- LiteSpeed Cache: Exclude from CSS/JS optimization
- Autoptimize: Add enhancer.webability.io to exclusion list
Performance Optimization:
- The Accessibility Enhancer loads asynchronously (won't slow your site)
- Only 12KB gzipped
- CDN-delivered for fastest loading
- Lazy-loads additional features as needed
Testing Your Installation:
- Open your site in an incognito window
- Look for the accessibility icon (usually bottom-right)
- Click it to open the accessibility panel
- Test a few features (high contrast, font size, etc.)
- Check your site's score in the WebAbility dashboard
Troubleshooting Common Issues
Accessibility Enhancer Not Appearing:
- Clear all caches (browser, CDN, WordPress, server)
- Check if you're logged in (some configs hide it from admins)
- Verify no JavaScript errors in console (F12 → Console)
- Disable optimization plugins temporarily to test
- Check if another accessibility plugin is conflicting
Plugin Conflicts:
- Security plugins (Wordfence, Sucuri) may block external scripts
- Add enhancer.webability.io to whitelist
- Some page builders need manual insertion in their settings
- Disable "Delay JavaScript Execution" in performance plugins
Multisite Issues:
- Network activate for all sites
- Or activate per-site for granular control
- Each site can have different Accessibility Enhancer settings
- Super admin can manage all installations
WooCommerce Specific:
- The Accessibility Enhancer may not appear on checkout without configuration
- Add to WooCommerce → Settings → Advanced → Page setup
- Ensure it's not excluded in your WebAbility settings
- Test with a test transaction to verify
