I have same problem.

I’ve mapped site with Multi-site plugin, probably this is cause…

Big thanks!!

I have added this filter to plugins/bp-custom.php and it seems to be ok now.

I have similar Warning: Cannot modify header information – headers already sent by (output started at …/functions.php:27) in …/wp-login.php on line 302

And how Brajesh Singh said the problem was in white spaces after ?> php tag in function.php

Thanks!
