I integrated WP 2.71 and the the bbPress v0.9.0.4.
I used the plugin to downgrade the cookies.
I no longer am able to preview posts in wordpress. I have another non-integrated blog and this is not an issue. Thus, it seems to me it is a bbPress issue.
I cannot login to both at the same time.
I want this to work but am finding the integration to be a problem. At times it makes me think WordPress and bbPress were developed entirely by seperate groups..
