 * I’m on WP 2.04 and wp-cache 2.19 version. each time I try to enable wp-cache 
   it gives me the following error… upgraded to wp-cache 2.22 but same problem… (
   haven’t upgraded to WP 2.1 cause of many formatting issues)
 * fopen(/home/ozdesi/public_html/wp-content/cache/wp_cache_mutex.lock): failed 
   to open stream: Permission denied in /home/ozdesi/public_html/wp-content/plugins/
   wp-cache/wp-cache-phase2.php on line 79
 * Any ideas on how I can resolve this issue with my present versions of wp-cache
   and wp…

 * Check to see if the permissions on your cache directory are set to be writtable
   or 777. It’s telling you that it can’t either open or write to the *.lock file
   up there.

 * You want to make the permissions on the cache directory to be the same as the
   smallest of these numbers: 644, 664, 666. The smallest one that works is the 
   one you want to use.
 * If none of them work, try 777, but if that fails, you’ll need to deal with your
   host to figure out how to allow it to write to the cache directory.

 * Hi,
 * i think its your Theme. I run 2 Blogs on my Server.
 * 1. Blog use Loops* to display postings (sort by cat) in the sidebar
    2. Blog 
   didn´t use Loops
 * On Blog 1 WP-Cache tell me “0 cached pages”, in Blog 2 WP-Cache works perfect.
   Now i change my Theme on Blog 1 and WP-Cache works fine here too.
 * Does anyone have a fix for this?

 * hi,
    have similar problem as described above: Couldn’t write to: /var/www/vhosts/
   mydomain.com/httpdocs/wp-content/cache/wp-cache-f7836ab2cb818d4ab947c21c672b3b1b.
   html /wp-content and /wp-content/cache/ are set to 777 and the same message appears
   even if I set 777 permitions up to /var.
 * Where is the real problem?
