[SOLVED] error saving with changed ACL group

Hi [I don't insert here the error notification, because in there are too much personal information of the db]

I tried to change a user from registrated to an other new ACL group (Testgruppe)
When trying to save (after I see saving is done) I get a red error notifications with a lot of data from db with:

Fehler
TRIGGER command denied to user '....'@'localhost' for table '#__it_people' SQL=UPDATE `#__it_people` SET registered='1', person_email="test@mysite.ch", person_name="Test -Person", modified_on="2016-03-31 06:38:38" , modified_by="admin" , username="tester" WHERE `user_id` = 786

_it_people doesn't exist in Joomla or CB. You've a 3rd party extension likely acting on Joomla user store (would be a Joomla system or user plugin) or CB profile update trigger.

thanks, it was issue tracker who made this problem.
