I am using WordPress 3.7.1, Buddypress 1.8.1, and bbPress 2.5.1.
My site is at http://www.tafaforum.com.
Everything was working fine until the last bbPress upadate, a couple of days ago. I've posted over there, too, but no response yet.
Our members can no longer post in the forum. It says they are not allowed. I've gone through the Member Roles, settings for everything, and can't find anything that would keep them from participating.
I disabled all the plugins, reinstalled the theme, buddypress, bbpress and the members plugin. I know that it is not a theme conflict because when I tested it on the default buddypress theme, the same thing happened.
The comment box is gone for all users in the forum except me, the administrator.
