Try also removing the  keywords from the last 2 blocks of CSS from your global.css, at the very bottom- perhaps this is what's affecting it (also the   part is missing semicolons after each line).

Other than that, it doesn't seem like the wiki's common.css has anything that can override it. So try updating your global.css and if it doesn't work, clear your cache just to be sure. if this still happens, try opening your console to see if Wikia's throwing any error messages, or inspect the links to your userpage to see if there's any other css code that might override the custom one.
