I got a hack for it if you are using MySql 5.5.
It reported on trac at https://bbpress.trac.wordpress.org/ticket/1486
Change TYPE = MYISAM to ENGINE = MYISAM in your bbPress installation’s bb-admin/includes/defaults.bb-schema.php
I have the exactly the same problem. I’m using MySql server version 5.5.12 on iis . When I look at database from phpMyadmin. bbPress post tables are missing. So although everything fine on forum, I can’t view post nor add new post.
