Hello! I found a problem after upgrade. mysql> SELECT GROUP_CONCAT(groupid) AS groups FROM `sys_group` WHERE client_id IN (SELECT client_id FROM `client` WHERE client_id=48 OR parent_client_id=48); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'groups FROM `sys_group` WHERE client_id IN (SELECT client_id FROM `client` WHERE' at line 1 Please check this. Mysql server version is 8.0.40 Regards Attila
