I’m having the same problem here. When user enters nickname and email address to register, they get redirected to the “default_site_domain/wp-signup.php“, where they have to re-enter everything. It’s very confusing for users wanting to participate on forums to say the least.
This situation also creates a problem for when a site with forum uses different language than the default site, as mentioned here.
Can one of the bbPress developers please give us some pointers, or at least tell us that this is not a common problem and we’ll have to figure out why this is happening on our own? We love bbPress and we’re hoping now to get some love back. 🙂
@jeffacubed Have you made any progress with this matter? I’m still researching…
Oh, and I’m running WordPress 3.9 Multisite, bbPress 2.5.3.
