- Last updated on: January 15, 2026
Font Awesome icons are widely used in WordPress websites for menus, buttons, social icons, and UI elements. However, many users face an issue where Font Awesome icons are not showing, or only empty squares/circles appear.
In this guide, you’ll learn all possible reasons and complete fixes to solve Font Awesome icons not displaying in WordPress.
Common Issues When Font Awesome Icons Don’t Show
1. Icons show as empty squares or circles
2. Icons appear as text instead of symbols
3. Icons work in admin but not on frontend
4. Icons stopped working after theme/plugin update
Reason 1: Font Awesome Library Not Loaded
The most common reason is that Font Awesome CSS is not properly loaded.
Fix: Add Font Awesome Manually (Recommended)
Add this code to your theme’s functions.php file:
function load_font_awesome_icons() {
wp_enqueue_style(
'font-awesome',
'https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.5.1/css/all.min.css',
array(),
'6.5.1'
);
}
add_action('wp_enqueue_scripts', 'load_font_awesome_icons');
Refresh your site and check icons again.
Reason 2: Using Wrong Font Awesome Version
Font Awesome 4, 5, and 6 use different class names.
Incorrect Usage
<i class="fa fa-facebook"></i>
Correct Usage (Font Awesome 6)
<i class="fa-brands fa-facebook"></i>
Reason 3: Plugin or Theme Conflict
Some themes and plugins block external CSS libraries.
Fix Steps:
1. Disable all plugins
2. Check if icons appear
3. Enable plugins one by one
4. Identify the conflicting plugin
Cache & optimization plugins are the most common culprits.
Reason 4: Font Awesome Loaded Multiple Times
Loading Font Awesome multiple times can break icons.
Fix: Remove Duplicate Loading
Add this to functions.php:
add_action('wp_enqueue_scripts', function () {
wp_dequeue_style('font-awesome');
wp_deregister_style('font-awesome');
}, 100);
Then load only one version using CDN (as shown earlier).
Reason 5: Icons Not Showing Due to Caching
If you are using cache plugins like:
1. WP Rocket
2. W3 Total Cache
3. LiteSpeed Cache
Fix:
1. Clear website cache
2. Clear browser cache
3. Disable CSS minification temporarily
Reason 6: Incorrect HTML or Missing Icon Code
Always verify the icon HTML.
Example:
<i class="fa-solid fa-share-nodes"></i>
Use official icons from:
👉 https://fontawesome.com/icons
Reason 7: Font Files Blocked by HTTPS or CORS
Mixed content issues can block icon fonts.
Fix:
1. Ensure your site runs fully on HTTPS
2. Use HTTPS CDN links only
3. Check browser console for errors
How to Test Font Awesome Properly
Add this test code inside a post or page:
<i class="fa-solid fa-heart"></i>
<i class="fa-brands fa-whatsapp"></i>
If icons appear → Font Awesome is working
Best Practice for WordPress (Recommended)
✔ Use CDN instead of plugin
✔ Load only one Font Awesome version
✔ Avoid loading via theme + plugin together
✔ Always match icon class with version
Conclusion
Font Awesome icons not showing in WordPress is a common but easily fixable issue. In most cases, the problem is caused by missing CSS files, version mismatch, or plugin conflicts.
