    Hi there we have the issue, that the Cache repeatedly gets deleted, to no obvious reason to us.

    We have set the following settings:
    – Caching On
    – Cache Delivery Method Simple
    – ?Disable caching for logged in visitors
    – Don’t cache pages with GET parameters.
    – Compress pages so they’re served more quickly to visitors.
    – Cache rebuild. Serve a supercache file to anonymous users while a new file is being generated.
    – 304 Browser caching.
    – List the newest cached pages on this page
    – Cache Timeout: 0
    – Not Caching tags, search pages, Author pages
    – Rejected URL Strings: as recommended plus /shop, /cart, /checkout etc
    – No CDN
    – Preload every 1440 mins, preload all posts, Preload mode, Preload tags

    We do also have a cron-job activated on the server side, that should call up pages every 30 mins.

    What is the issue here? Why is the Cache getting deleted repeatedly.

    Thanks for your Help

    Makoto

    Hi there,

    It seems like you’ve already configured quite a few settings to optimize the caching on your site with WP Super Cache. However, there might be various reasons why your cache is being cleared unexpectedly. Let’s go through a few troubleshooting steps to pin down the cause.

    1. Check for Conflicting Plugins: Other plugins might be interacting with WP Super Cache and causing the cache to clear. Deactivate other plugins temporarily to see if the issue persists.
    2. Verify Cron Job Configuration: Make sure that the server-side cron job is set up correctly and not accidentally clearing the cache when it runs.
    3. Examine Cache Timeout: Although you’ve set the Cache Timeout as 0, which should mean no automatic expiry, double-check if there’s any feature or setting that considers this value as invalid and defaults to regular cache clearing.
    4. Look at Preload Settings: Since you mentioned that you’ve set preload to happen every 1440 minutes, ensure that this action doesn’t clear the entire cache before preloading.
    5. Check the Server Logs: Server logs can provide information on what processes are triggering the cache to clear. Review them to find any recurring patterns.
    6. WP Super Cache Settings: Within WP Super Cache settings, there might be an option that is set to clear the cache regularly or under certain conditions. Revisit the settings to ensure there isn’t a misconfiguration.

    If you could provide the URL of your website, that would help us further investigate the issue.

    Also, if the cache is being cleared due to some user actions on the website, consider checking if user roles or configurations within WordPress are linked to cache clearing routines.

    I appreciate your detailed information, and with a bit more investigation, we should be able to pinpoint the cause of this issue.

    Reply in this thread with any further details or updates you have, and we’ll take it from there.

    Thank you!

    Hi @mbruderer,

    Do you have updates about that? We usually close inactive threads after one week of no movement, but we want to make sure we’re all set before marking it as solved. Thanks!
