Re: This username does not exist
Does bbPress need to be ‘reinstalled’ after going backwards to WordPress 2.5.1? Like, if the bbPress installation made changes to the database with WordPress 2.6, then you rolled back to WordPress 2.5.1, you would lose the changes that bbPress made to the wp_users and wp_usermeta table, right? Would you need to reintegrate with the WordPress 2.5.1 database?
