You should check if the table wp_bb_posts has been created in your database. Otherwise, you should create it manually:
CREATE TABLE IF NOT EXISTS wp_bb_posts (
post_id bigint(20) NOT NULL auto_increment,
forum_id int(10) NOT NULL default 1,
topic_id bigint(20) NOT NULL default 1,
poster_id int(10) NOT NULL default 0,
post_text text NOT NULL,
post_time datetime NOT NULL default ’0000-00-00 00:00:00′,
poster_ip varchar(15) NOT NULL default ”,
post_status tinyint(1) NOT NULL default 0,
post_position bigint(20) NOT NULL default 0,
PRIMARY KEY (post_id),
KEY topic_time (topic_id, post_time),
KEY poster_time (poster_id, post_time),
KEY post_time (post_time),
FULLTEXT KEY post_text (post_text)
) ENGINE = MYISAM;
Hope it works.
It did for me.
