Re: A bit of advice needed
I would install bbPress latest which is 0.9.0.2 and WordPress latest which is 2.5.1. The big change with WordPress 2.5.* and bbpress 0.9.* was with the cookies. If you have only a few test posts, I would just install WordPress fresh (or upgrade your WordPress installation) then install bbPress fresh. Integration is totally different now, no more plugins.
