Thread:Project:Support desk/Pages not loading correctly sometimes - Cache problem?

MediaWiki	1.21.1 PHP	5.4.9-4ubuntu2.3 (apache2handler) MySQL	5.5.32-0ubuntu0.13.04.1

URL: http://elwiki.net/

I don't know if this is supposed to be a common problem, but since I enabled memcached and file caching this often happens randomly when I try to load a page: http://i.imgur.com/Z70fMDd.png

Is there a way I can fix this? Thanks.
