I see the same using the modern skin on (all) Wikimedia wikis. Modern.css and common.css are not loaded. This breaks infoboxes and other customised CSS.

Perhaps it was this one (http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=38116) who broke it?

just adding two exemplary links here to make sure you note the impact:
http://de.wikipedia.org/w/index.php?title=Wikipedia:Hauptseite&useskin=modern (German Wikipedia's main page)
http://de.wikipedia.org/w/index.php?title=Bayern&useskin=modern (random article with infobox and other stuff that isn't rendered)
… lots of grumbling all around especially by 'modern' users

Sorry, I forgot to update those two skins for the new SkinTemplate CSS handling. :(

r38139 fixed this for Modern...

r38143 fixed Simple.

Note there's lots of general weirdness with Modern, as it doesn't use the same IDs and classes as everything else; it should get a major overhaul at some point.

Plus final tweak to Modern in r38146, r38147...

This change breaks the layout of flagged revisions (see http://de.wikipedia.org/wiki/Bild:Weissraum.jpg). We turned off the box for most cases, but you can see there http://de.wikipedia.org/wiki/Am_Rande_des_Rollfelds that in particular infoboxes get real problems.

Comment #6 seems to be unrelated; screenshot is of MonoBook skin. If a problem persists, please provide more info on a dedicated bug.
