First, is the Wuthering sub-skin supposed to look like in the screenshot? The dark grey does look a bit off :)
But, I would simply change to another theme *if* the theme selector in the side bar would let me... Tried to switch to another theme and ended up with an empty page under the url http://wedge.org/?http://wedge.org/theme=1 or something more weird like http://wedge.org/?http://wedge.org/theme=1_c2tpbnM=
The empty page is probably a result of some error not displayed - maybe it's just in the log.
Side note: switching themes in the profile does seem to work.
