I had the same kind of problem, but with a different version of the functions.php file. Robin pointed out this post, and it worked after I adapted it slightly for my version. See my fix, which “zooms in” on the code a little further to more clearly point out the change, at https://bbpress.org/forums/topic/forum-still-not-working-right/#post-146790
