Re: 404 Error in front page, please help!
We’ve been having a related discussion in this thread. Are you using BlueHost as well? It does not really matter. The lessons in the link are the same.
The requested URL /community/members was not found on this server.
Do you have the default member theme (bpmember) installed in /wp-content/bp-themes/?
Group, Members, Blogs, Registration, does not work.
I assume registration is working fine now because I just visited your site and you have a newly registered member–a test account, I assume. The time on your OP clearly indicates that you started this thread before you registered that new account.
Finally, please go through this list of questions.
