WPMU Page Keeps Getting Stuck

I'm currently publishing HalalPress.com.

I've received many reports that the form to create new blogs and users is not working. I tried it myself, and it is not working. The page gets stuck at the registration. You do receive an e-mail, but the activation email link says an error has occurred.

Could someone help me? :slight_frown: I'm using WPMU, BuddyPress, and the Social theme from this forum.
