OK, so this is a clean install of .9 bbpress. Here is the location of the forum:
Only the /forum/ part of the website is visible because I have put the rest in maintenance mode. The admin section of the forum displays fine for me and I have no problems at all. Also, I loaded the forum page in Safari and Internet Explorer, where they looked fine. However, when I clicked on the single topic that you see, it took me to what looks exactly like http://gsupoetry.com .
I have no idea what the problem is...
