I have turned on "Rename wp-signup.php". However, the note that reads, "(Not Buddypress compatible)," has me curious. How exactly is this feature not compatible with BP?
For my site, I set the Registration page in BP to 'None'. This doesn't allow anyone to view the BP signup form by going to wp-signup.php directly.
I have tested creating accounts and it seems to work fine. I just want to make sure I'm not missing something here.
