I just upgraded my blog to 2.3.3 and now the posts and columns won't display properly in Firefox (yes, I cleared the cache and refreshed). However, it displays just fine in IE7. I'm pretty sure I followed all the upgrade instructions to the letter, but I guess I may have missed something but I suspect if that were the case I assume I'd see the same problem in IE7. Also, I tried several different themes (including upgrading my K2 theme) to see if there was a compatibility problem, but no luck. Any ideas/suggestions???
