It works correctly now, but the issue is the paths for images/css are wrong if you go to a page like
http://www.gfx-help.com/test1/test2/
I had a replacement variable for image paths which pointed to "images/theme", I changed that to "http://www.gfx-help.com/images/theme" and thought that would fix it, but it didn't help. Perhaps it's happening due to the css paths being incorrect?
