Okay, I bought and downloaded xenforo yesterday, and the installation went trouble free. Until i wanted it to be www.mydomain.dk/forum. Because it wouldnt show up on that page. But instead on www.mydomain.dk/forum/index.php. I went in options, and changed the setting for SEO - and got it to redirect. So when i went on /forum/index.php, i got to /forum/ - but nothing would show. In the source-code nothing will show, and im getting 304 error.. I really have no idea what to do. If any more informations is needed, feel free to comment.
