Thread:Project:Support desk/Link style issues after upgrading to MediaWiki 1.19.0

After upgrading from MediaWiki 1.17.0 to 1.19.0, all of my links are underlined, and links to pages that do not exist look like this: Some Page ? Does anyone have any thoughts on what could cause this problem? I've checked Common.css and Vector.css and I don't see anything that would cause this behavior.
