The vector skin on the wikitech wiki is displaying weirdly because apparently it is running a outdated version so it should be updated.
Also the overall MW install seems to be a bit behind compared to what is running live so that should probably be fixed as well (with the WF wiki being "1.16alpha-wmf (r55640)" and en.wiki being "1.16alpha-wmf (r59858)".
