Thanks for the tip.
Info for the people having the same problem, there are two tables in mysql:
bb_usermeta
wp_usermeta
After integration (in “my case”) bbpress was fetching data from the wp_usermeta. I added new record: user_id = X, meta_key = ‘bb_capabilities’, meta_value = ‘a:1:{s:9:”keymaster”;b:1;}’ (where X = wp admin id, in my case = 15). Done, I have got all options.
