Frontend not loading with WP-Optimize caching enabled

Hi guys,

For one of our websites the frontend doesn’t load at all when using the caching functionality of WP-Optimize. We’ve enabled WordPress debugging by setting the following in wp-config.php:
define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_DISPLAY’, false );
define( ‘WP_DEBUG_LOG’, true );

However, no error logs are generated when visiting the frontend. When I click Inspect and go to the Network section, all it shows is the root directory and that it’s pending indefinitely. The only thing that seems to load is the favicon, and only for the homepage. On every other page nothing loads. The weird thing is that the favicon doesn’t show that the website is loading either.

The backend works fine and when signed in, the frontend also functions normally. I assume the frontend works only when signed in because it doesn’t use it’s cache to load the pages.

Any help will be greatly appreciated!

Kind regards,

Frank
