Re: Installed fine but no automatic login
as you can see in many post outta there, bbpress 0.9 and wordpress 2.7 aren’t integrated well to each other without a special plugin. you have three options to get your integration working:
1. upgrade bbpress to unstable 1.0 alpha version
2. downgrade you wordpress to 2.5
3. use a plugin to get your current versions working together.
