Re: register.php not working (but wp-signup.php does)
Ok after further testing, my earlier belief that wp-signup.php works was wrong. I just realized that I must have tried wp-signup.php while signing up with a gmail address (which works).
Considering that the only entry that I make for the admin email address is to add the email address in the site admin options, do I not need to add a user name and password into WPMU for the email address to allow WPMU access to send emails? I am using a non gmail domain hosted on google apps as the support email in the admin.
Btw, I realize that with wp-signup.php not functioning as well, this is no longer a buddypress issue but probably a WPMU one. However, I would still be grateful for any help I can get from these forums. I will continue my search at WPMU forums also. Thanks.
