Once I create new template (first screenshot) with link to another template, I got this one error:
Added new host [CUS_ARM_Template]
Undefined index: templateid[/usr/local/share/zabbix/php/api/classes/class.ctemplate.php:836]
Error in query [INSERT INTO hosts_templates VALUES (31,10082,)] [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 ')' at line 1]
