bbPress.org

You have the URI to the site wrong somewhere, I think. Your forum is here:

http://gpsobsessed.com/forum/bbpress/

But I think you want it in one of these two places:

http://gpsobsessed.com/bbpress/

http://gpsobsessed.com/forum/

So, somewhere it’s gotten mixed up. At the full URI, the path to the stylesheet is wrong as well, which is why it looks so strange there.
