I’ve tried several of those “object cache” plugins with Xcache on my server.
However if I enable the option in WP Super Cache that supports object cache, I get this error:
Fatal error: Call to undefined function xcache_unset_by_prefix() in /home/technigh/technightowl.com/radio/wp-content/plugins/tribe-object-cache/lib/xcache/object-cache.php on line 177
So is there something in Xcache or any of those plugins that is causing this? Plain English answers always help.
