# Troubleshooting CDN Issues¶

You can narrow down CDN issues through the following steps:

• Visit the CDN URL and verify that it is accessible
• Check your CDN settings
• View Page Source, and verify that links are indeed pointing to the CDN URL.

## Bypass CDN in AJAX¶

If you have a conflict, and you need to bypass CDN functions in AJAX, you can either add some code to your theme's functions.php, or you can call the appropriate filter when using AJAX.

### In the Theme's Functions¶

Add the following to your theme's functions.php file:

defined( 'DOING_AJAX' ) && add_filter( 'litespeed_can_cdn', '__return_false' );

### Call the Filter¶

When using AJAX, you can call the above filter, and return false.
