I'm using the latest 0.9.2.11 release and seeing the following error when w3tc is trying to get a page from memcached:
Fatal error: Call to undefined function apply_filters() in /path/to/wp/wp-content/plugins/w3-total-cache/inc/define.php on line 119
Seems like a bug to me, would appreciate some help with which version to roll back to or if I can patch it myself for now?
Cheers!
