[resolved] WP Super Cache breaks website into error 500 when working in admin panel (4 posts)

    Hi guys,

    I have an issue with WP Super Cache. It installed correctly then I used the recommended settings for caching. After activating the plugin, it works fine with caching and everything (I can see the cached html files in the cache directory) BUT:

    when browsing the admin area, after about 2 clicks the entire website goes down throwing a 500 Error. If I issue a sudo service php5-fpm restart it works fine again until I log in into admin area. I could not find anything in the logs as of yet and have no idea how to tackle this problem. I tried also uninstalling/installing the plugin and also the FAQ section but to no avail.

    Any help is greatly appreciated!

    Have you enabled debugging to narrow down the problem? Have you tried deactivating other plugins?

    If restarting PHP fixes the issue temporarily, then try removing opcode cache (APC, Xcache, or whatever) entirely. You may also want to try the suggestion provided earlier by @rowelld .

    Thanks rowelld,
    I already tried to exclude other plugins to narrow the cause but it seems that WPSC is creating the issue.

    Disabling APC was the way to go in my case. Commenting out the ;extension=apc.so in /etc/php5/conf.d/apc.ini seems to be solving the issue. No crash yet ;).
    Cheers Pothi Kalimuthu!
