BuddyPress: Can't Register New BP Account, Help!

I don’t know why, but users can’t register a new member account with buddypress on my site now. Here is my registration page. After entering in details and clicking the submit button, it just reloads the same page again. Why would this be happening? This is very bad. Could someone try registering a new user on this page? This is the case for all sites in my network. Register page just keeps reloading and I can't create new users. Thanks!!
