No redirect after join

Hi,

After a new user fills in the sign up form, my site (tonguetide.com) is not redirecting them to the member.php page like it used to. It actually seems the join button doesn't work at all.

Any ideas?

Regards.

Scratch that. I fixed it. I had a php expression attempting to stop spammers using numbers in first and last name fields that was upsetting things.

If anyone has a suggestion on how to do this properly that'd be great. I had previously tried the below:

elseif(preg_match('#[^a-z]+$#i', $firstNameSignup)){
            $firstNameSignupError ="Your first name cannot contain numbers or symbols, you entered ". $firstNameSignup;
            $firstNameSignup ="";
        }
