  • I was about to post the same question. Expired files need to be removed manually.

    Using WP 2.7 and Super Cache 0.8.7


    I’ve been grappling with this exact issue for over a month. Have to go in and manually delete the expired files, otherwise my site doesn’t serve up super-cached pages….

    What platform are you on? Windows or Linux? And since I’m still very march in the dark on what the problem is…Did you do the symlink for advanced cache file and/or does the wp-content have the proper access? Do you get a warning on the super-cache settings page?

    I am using a Dreamhost server and no matter what I do the files are not removed.


    Seems enough people are reporting this that there must be some common issue. The plug seems to work for me except for this one bug, it must be traceable to something being configured incorrectly???

    I setup the email debugging and it says
    “Cache Expiry cron job failed. Probably mutex locked.”

    Are you guys seeing the same thing? I am glad he put in the debug mode but I dont know what the message means!

    Could this have something to do with daylight savings? WordPress general settings says

    Unfortunately, you have to manually update this for Daylight Savings Time. Lame, we know, but will be fixed in the future.

    Just wondering if this doesn’t match garbage collection schedule, it might not happen

    blogrelations – No, DST would only have affected a cron job on the night things changed. If you have problems with clearing out expired files then disabling file locking will help.

    @donncha – i am still having this problem. I’m on Dreamhost PS. I have this on my access.log:

    – [14/Aug/2009:00:34:23 -0700] “POST /wp-cron.php?doing_wp_cron HTTP/1.0” 200 628 “-” “WordPress/2.8.4;

    That means wp-cron.php is accessible, there’s no 404 error.

    But my expired super cache files are not deleted. I have to manually delete them. There’s no problem with the WP-Cache garbage collection. Only on WP-Super-Cache.

    I tried disabling file locking as suggested, but I got the “blank screen of death” after making $use_flock = false.

    Please help.

    My problem was already solved. No need to reply. The solution: I just unchecked the “Coarse File Locking” option.
