Sorry about that. For some reason, the Drain Hole plugin seems to deactivate itself from time to time. Check again, you should see the download link now.

Hi, I couldn’t find the link to download the plugin it shows “[drain file 16 show default_show]” instead.

Thanks!

I’ve found the problem. Don’t know why and don’t know where, WP adds “users”,”userlogins”, “usermeta” to the “global_groups” array and so your plugin store those data with an empty prefix . So, when you run multiple WP on multiple virtualhosts on the same machine, you’re not able to have 2 admin user (or users with the same login) accesses cached at the same time. “Global_groups” (necessary on a WPMU installation that shares authentication parametrs between sub-blogs) should be empty in this case.
As a workaround i’ve patched your code from
function wp_cache_add_global_groups( $groups ) { global $wp_object_cache; $wp_object_cache->add_global_groups($groups); }
to
function wp_cache_add_global_groups( $groups ) { global $wp_object_cache; return; //$wp_object_cache->add_global_groups($groups); }
It resolves my issue but don’t know if this works on a WPMU installation also (as you manually add global groups at WP_Object_Cache object creation.

Only one note: if I clear cache content fromXcache admin panel, WP admin access works again.

Hi, i’m using this plugin on WP 2.8.6 and it seems to work very well, lowering query numbers to a 1/3 factor (from about 60 to about 20). But I notice a strance behaviour: admin password is not recognized at all and i must reset it to obtain admin access again. With all other users, there are no problems.
Can someone point me in the right direction to resolve this issue?

Thanx!

I know this post is a year old, but it’s the best/most recent plug-in I could find for using xcache with WP. I just installed it for WP 2.8.4 and it appears to be working great. I don’t quite understand how WP recognizes/uses the plug-in just by uploading the file to the wp-contents folder, but I’m glad it does. Thank you for sharing your updated plug-in.
