For some odd reason, the TwentyTen theme doesn't display correctly in Firefox 3.6 or Chrome, but works in Internet Explorer 8 fine. I've cleared my browers' caches, restarted them multiple times, and I get the same result each and every time: A web site that looks like a throwback to the early '90s. Something isn't rendering correctly in WordPress, and I don't know why that is. The site is at theretriever.org. Any insights are appreciated.
