There's this weird thing about MediaWiki:Common.js in my wiki (on which i'm a code editor, not an admin). Whenever i try to change the content of Common.js, loading leads me to  with a blank screen, my edit is not published and i'm getting a status error of 500 (Internal Server Error). I tried the same on my test wiki and got the same result- even when trying to edit Wikia.js. However, i was able to replace the page content with a very short code (to be precise, replacing the content with "1" by mistake :P). I've also asked an admin to try and edit the page, and he's experienced the same problem. Did wikia start limiting the page size of MediaWiki pages or something, or is this something else? I would have asked them via Special:Contact but was too lazy to wait 2 business days, if you know what i mean.
