BuddyPress.org

I’ve determined that the warning is generated when /wp-signup.php is accessed (mostly by spam bots). Can’t find white spaces anywhere. Is /wp-signup.php supposed to redirect to /register or to a blank page?

My site and the other listed both display the Registration Form and the PHP Warning: Cannot Modify Headers:

http://ttacconnect.org/wp-signup.php

http://memomu.com/wp-signup.php

These sites result in an blank to semi-blank page:

http://startupweekend.org/wp-signup.php

http://nourishnetwork.com/wp-signup.php

http://morgansjourney.org/wp-signup.php

http://poetrypress.org/wp-signup.php

Should /wp-signup.php result in an blank page or the registration form? Will resulting blank page eliminate the ‘Cannot Modify Headers’ Warnings in error_log? What is the fix? Thanks!
