Missing Sidebar

Yesterday the firesave7 virus got onto all of my sites – both WP and MediaWiki. I was able to clean it up, but now I’m having a problem with one of my WP blogs – http://thepetwiki.com/blog/ I can’t get the sidebar to show up. It works on FireFox, but not on IE or Chrome. I’ve tried reinstalling WordPress and the theme that I’m using, but nothing seems to help. This problem shows up on all themes that I’ve tried. I am not having this problem on any other WP blogs that I run, even though all of them were problematic. Any insight would be great. Thanks!
