    I am experiencing problems with internal 500 error on our WP site running 6.2.2.

    I have enabled debug and see this message in the logs.

    Is there anything I can do?

    Hello @tobyw7

    Thank you for reaching out and I am happy to assist you with this.

    Can you please confirm that the problem persists if you temporarily disable W3TC?

    Thanks!

    Hi Marko

    I will deactivate the plugin for a period of time and update with the results. It seems that the debug log is flooded with this error message currently.

    I also noticed the version of PHP on this site was outdated so have upgraded to 8.2 – will monitor.

    Hello @tobyw7

    The  wp_cache_flush_runtime is not a 500 error and it’s related to a Object Caching if enabled using Disk.

    Do you have any fatal errors besides the  wp_cache_flush_runtime that may be logged at the moment you are getting 500 errors?

    Thanks!

    I’ve checked the log but other than a lot of PHP deprecated messages can’t see anything that stands out. The same errors happened before the last outage period – each time it’s around 5 minutes. Trying to rule out various pieces.

    The 2 related to W3TC are late_caching and nginx_memcached

    @vmarko the other half of the error message if it helps –

    Your object cache implementation does not support flushing the in-memory runtime cache

    Does it mean anything?
