My friend cant get guest autoninvite working :

after !autoinvite on bot gives:
MySQL ERROR(# 1) on query: INSERT INTO mercsbot_preferences (pref_id, owner, value) VALUES ((SELECT ID FROM mercsbopt_preferences_def WHERE module="autoinv' AND name='recieve_auto_invite' LIMIT 1), -2089211650, 'On")


also preferences !preferences show autoinv
just gives just topic ( ::: Preferences for autoinv ::: )

nothing else same with other preferences windows,

Bebot is 0.67
