@tongzie I checked your website and it’s obvious that the assets (CSS/JS/Image files) are not loading due to the wrong CDN settings that you set, most likely in WP Rocket. The plugin (WP Rocket) does create the cached CSS/JS, but the CDN you set which is //Bartalks.b-cdn.net/ does not have this files on its server – if you replace this path with the local one which is //wordpress-400507-1422769.cloudwaysapps.com/, then the files are loading fine.
Moreover, if you access the URL with any query string such as /?nocache (e.g. https://wordpress-400507-1422769.cloudwaysapps.com/?nocache) you will notice everything works fine. The same goes for https://wordpress-400507-1422769.cloudwaysapps.com/?wpacu_no_load which completely deactivates Asset CleanUp on page load (for debugging purposes).
Based on my experience, it’s the page caching that needs to be cleared there and this has nothing to do with Asset CleanUp. When you’re saying uninstalling the plugin fixes the site, it could be because whenever a plugin is deactivated, WP Rocket (or any other page caching service you’re using) clears the page caching and when you view the page in Incognito (as a guest), then it loads the latest version of it, that was just re-cached.
Please check this again and let me know if things are still unclear.
@izjakic Perhaps your situation is the same here. Can you check that? I don’t have your website’s URL to check it out. You can send it via https://www.gabelivan.com/contact/ if you’re not comfortable sharing it here in the forum.
