My hoster has setup the server with memcached and I use
$wgMainCacheType = $wgParserCacheType = $wgMessageCacheType = $wgSessionCacheType = CACHE_MEMCACHED;
Memcached works in the wiki. But php info reads nothing about memcached / memcache.
Does MW use some fallback in such case?
MW 1.2.5.5 | Ubuntu 14.04.2 LTS | Plesk 12 | PHP Version 5.5.9-1ubuntu4.11 (Apache Module) | memcached 1.4.14
