I was play with my yourdeafvlog.com and I test click on upload or friends. It will not display page. Possible inside script redirect will not work right. That's my guess. How I know? I check your video.bizhat.com and I click on upload and it will redirect to video.bizhat.com/signup.php?next=upload but my yourdeafvlog.com click on upload will stay upload.php not redirect to signup.php?next=upload without login. That's my guess.....

By the way, I sent pm you.
