Multisite – when user creates new site, page won't load.

I’ve installed Multisite, Buddypress and BBpress. All are up todate including the WordPress install.

User gets the

Congratulations! You have successfully registered a new site.

http://mysite.com/site1/ is your new site. Login as “Admin” using your existing password.

Once I click on the new provided link, the page gets re-directed back to the user http://mysite.com/members/currentuser/ and not the new site.

Also, the Login link won’t load and gives the following error message when trying to access http://mysite.com/site1/wp-login.php :

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

This problem can sometimes be caused by disabling or refusing to accept cookies.

I’ve unplugged all the plugins (excluding WPMU Dev and Buddypress) and tried creating the site a new site and now the new page link will load incorrectly on a white background and raw links. The login still gives me the same Firefox error.

Can someone please help me.
