New user registration for bbpress sends the user to the main website page.

Hello there!

I am setting up a forum for a client, and everything seems to be good so far, except... When a new user tries to create a new account to join the forum, he is redirected to the Multisite's main domain with an error message saying Registration has been disabled. Is there any way the user can register without ever seeing or having anything to do with the main site?

I know something is possible, since one of the websites on the network is an e-commerce website and new users sign up and buy without ever seeing the main website.

You advise and help is greatly appreciated.

Regards,

Paul
