I installed bbPress 2.0.2 on WordPress 3.3.1. Embedded it in the site of a customer. There are some forums created. All are Forum, Open and Public. Some topics are added by an Administrator. So far everything ok.
When a user with role Forum Participant logs in, it can access the forum, but no topics are shown:
This forum contains 4 topics and 0 replies, and was last updated by xxx 1 min ago.
Oh bother! No topics were found here!
Administrators do see the topics. What is happening here?
