I just found out that my site has been broken for a few days (chrisblackwell.org). The problem is (and why I didn’t see it until now) it only breaks when I’m NOT logged in, only on a post page (an article page), and only in FireFox. I’ve checked it in both IE8 and Chrome and it works fine. I’ve never seen this kind of rendering bug.
I’ve attached a Chrome screenshot and a FireFox screenshot to show the difference.
Firebug showed it the way I described so … you are missing something, whether a missing close tag or whatnot :). Validate your code to find these things.
YOUR THE BEST!!! That was it! I was calling a php function and it wasn’t seeing the closing </p> I put it outside the loop and it fixed the problem. THANK YOU SO MUCH!
