After an update from 1.13.x to 1.14, MediaWiki stopped to take the MediaWiki:Common.css file into consideration. Placing its content into the skin's main.css file works as a fast workaround.
Can you provide more information? Is "$wgUseSiteCss = true;" still the default and not overridden Is the page correctly being called in something like <link rel="stylesheet" href="/w/index.php?title=MediaWiki:Common.css&usemsgcache=yes&ctype=text%2Fcss&smaxage=2678400&action=raw&maxage=2678400" type="text/css" /> in the page source? If you go to that location, does it show, or do you get "Raw pages must be accessed through the primary script entry point." and/or some other errors?
I ran into this same problem only to find out it was a custom skin which was causing the problem. Seams like there has been some MW skin changes from 1.13 to 1.14. After fiddling with the custom skins <head> tag, all is well. Just some food for thought.
You're right, the reason was in our own skin based on MonoBook from MediaWiki 1.12 -- after I rebased the skin to MonoBook from 1.14, everything works as expected.
