Thread:Project:Support desk/Enabling CACHE ACCEL causes fatal exception of type mwexception

Hello everyone,

I've been reading into optimizing my mediawiki site and tried enabling $wgMainCacheType = CACHE_ACCEL; into the code. However, if i add this line, my wiki does not function at all and reports "[2fd7b859] 2013-05-13 21:39:56: Fatal exception of type MWException"

Please advise, thank you!
