Sir thank for your advice,
i already change all of level words in register cp and i got this error
MySQL query['register.php'] :
INSERT INTO veronicacp.register_log (Date,account_id,userid,group_id,ip) VALUES (NOW(),"2000001","gmevent1","0","118.96.114.243")
since you edit all the level into group_id. you also need to edit the register_log. find the level and change it into group_id.
Problem Solved, Tx brynner
