MediaWiki intermittently displaying garbage

  apache, cpanel, mediawiki, php

Sorry if i’m asing an obvoius question, I’m fairly new to PHP and this website. I’ve recently noticed that a mediawiki engine that has been running uninterrupted for about six months has started doing odd things. It intermittently displays garbage characters on PC’s and will not load at all on a mobile device, regardless of browser. It’s only modifications were the cite plugin and disabling user creation in the config, although it was running fine for about six months with these. I’ve cheched the MIME types, and they’re fine. It almost looks like binary. Picture included: like this I have no idea what’s going on, and I’m fairly new to this and don’t want to loose all my pages.
