Re: install for beginner
WordPress 2.7 and bbPress don’t integrate. But that’s not why you’re having trouble integrating the two. If bbPress can’t connect to the database, it’s because one of the connection details is incorrect, or was left out. People sometimes forget to enter the hostname in the database connection details since I think it’s called “advanced database settings” or something. If you need to enter a hostname and have not, that’s likely the connection problem.
You do not need to create a different database for bbPress, and integration is easiest when you use the same database.
