Trouble clearing the cache from a script…

  • I’m trying to clear my WP Super Cache from a script. For some reason wp_cache_clear_cache(); isn’t working. Nor is:

    prune_super_cache( $blog_cache_dir, true );
    prune_super_cache( $cache_path . ‘supercache/’, true );

    As far as I can tell, none of the above are having any effect on my cache at all.

    Is there anything I can try or test?

  • Have you tried the wp_cache_clear_cache() command? You could also enable debugging in the plugin. That should tell you a lot.

    Yes, I ran wp_cache_clear_cache(), no luck.

    And thanks for the tip about turning on debugging. I’m seeing some interesting lines in my log:

    What really has me curious is this one:

    09:09:50 [fname] Supercache caching disabled. Only using wp-cache. Non empty GET request.

    Does that mean I’m not using the WP Super Cache plugin for caching?

    Probably some plugin is populating the $_GET array on every request. Unfortunately you’ll have to disable each plugin or search through your plugins one by one to find the offending one.

    Are you still using wp-super-cache? Give the development version a go (download here) as I changed a restriction on clearing the cache that may have caused this problem.
