On clicking install it says

I use wp2.9.1 and stable bbpress 101

here is what i get

OOPS

BBpress is already installed

maybe u should upgrade

All I did was click the install button once

then went back to look at the step three settings and changed the advanced database settings to be wp_ instead of empty

everything else went according to hoyle

If you have wordpress installed in the same database with wp_ as prefix, then use bb_ as prefix for bbpress, else it would conflict with wordpress.

@Gautam

I don’t think so. Why it would?

I think that error occurs if you have bb_ prefix tables already. Can you check the database to see if that’s the case? If there are bb_ tables already, maybe you tried once before to install bbPress?
