Looks like your CSS isn't loading.  Can I have the link to your site?

I have seen this happen on my local a couple of times. I figured this was due to my ISP during download. Corrupted files in transit. The fix that seemed to work for me was to download a fresh copy of the forum software and install over the corrupted files.
Then when things start to look better I still ran the support tool under support.

IPS tech didn't figure it out.  I exported the default template from another site and imported it into mine and it went back to normal. Odd because I was using the default template, but for some reason it didnt' transfer over.
