    Hi @omusman,
    Thanks for sharing the screenshot of the console. Unfortunately, Error 524 means server timed out. Which means your server was unable to complete the request. It might be possible that your server is super slow and overcrowded and unable to process that request (as that is the most common reason). But again this is not a plugin problem. Just while writing to you, I’ve tested that feature again on a production site and it works perfectly.

    I will highly recommend you to check this Cloudflare doc link to understand the Error 524 more clearly: https://support.cloudflare.com/hc/en-us/articles/115003011431-Error-524-A-timeout-occurred#524error

    Hi @omusman ,
    thanks. Into the debug.log of the plugin, you should see a log that starts with:

    [cache_controller::start_cache_preloader_for_specific_urls] Adding these URLs to preloader queue:

    Can you please paste it here?

    There are array links with:

    `domain.com/?p=19520
    domain.com
    /?p=19520feed/
    domain.com/author/admin/feed/’

    these are the recent array, there are 5 of them like this with different category page and feed pages.
