Cached files seem to corrupt every week

    I use preload on WP Supercache.

    For some reason, my site seems to brake every week or so. The CSS disappears and the site becomes unusable.

    I’ve tried having “Refresh preloaded cache files every?1440 minutes” and still it breaks roughly once a week (or every 5 days). I set garbage collection to once a day also to try and see if that was effecting it.

    Also, I use Asset Cleanup to combine javascript and css. it could be something to do with this.. although I’m really not sure.

    The page is currently not broken – I’ve just reset the cache, this seems to correct it then I have to preload again.

    Any ideas? It’s most annoying as I can never work out exactly when the break is going to happen. Could it be to do with WP-cron?

    Any help appreciated.. PS if you need birthday songs, check out the site!

    Thanks!

    Hi @jimeny

    Troubleshooting caching and performance issues can certainly be complex and require some trial and error to resolve! A few things you might review to see if the cause can be narrowed down:

    Monitor your server logs: Your server logs can provide valuable insights into what may be causing your site to break. Look for error messages or other anomalies in the logs around the time that the site breaks to help pinpoint the source of the issue.

    Does the issue only happen when both WP Super Cache and Asset Cleanup are both active? If one or the other is deactivated for a time, does site still break?

    The Jetpack Boost plugin combines features of WP Super Cache with the ability to Optimize CSS Loading and Defer non-essential Javascript. It might be something to check out instead of running two separate plugins.

    Also, you might try installing the WP-Crontrol plugin to see if anything might be happening with Cron. WP Super Cache does rely on WP-cron in order to work properly.

    did you ever work this out?

    I’ve got the same issue and it’s beyond irritating! The site breaks and I cannot work out when it is going to happen, I then get customers using a broken site.

    I will have to try a different cache plugin and uninstall Asset Cleanup

    Many thanks

    Hi there @jimeny.

    Thanks for following-up with us.

    Having two site performance plugins activated on your site at the same time can definitely create some unexpected behavior.

    As my colleague mentioned before, it would be ideal if you could try keeping WP Super Cache activated and disabling other feature-overlapping performance plugins. You can then monitor the situation and see if there are any improvements there.

    You can also consult our resource on running plugin/theme conflict tests here: https://jetpack.com/support/troubleshooting-plugin-and-theme-conflicts/#troubleshooting-manually

    Let us know how it goes!

    @jimeny it’s probably Asset Cleanup as WP Super Cache doesn’t try to do anything with CSS files. Maybe that plugin is breaking CSS files randomly, and you wouldn’t know it except that WP Super Cache is caching the broken pages.

    Next time it happens, take a careful look at the source code and even better, download a copy of the page and the CSS. Then clear the cache and view an unbroken page. See what differences there are in the HTML and CSS. Maybe there’s something obvious. Look in the web developer tools of your browser to see if any CSS files aren’t loading properly.
