I've installed ox on a subdomain but many of parts doesn't work properly. I read everything about htaccess in this forum but non of them helped me. 

here's my ox link:

http://social.svus.ir

I've spend more than 15 hours to solve this problem!! I really don't know what else I have to do. :(

if http://social.svus.ir didn't work or theme didn't load try http://social.svus.ir/index.php

Thanks

Here's a sample of my htaccess, all commented lines have been tested each time.
