I use php page to create host, hostgroup, user, etc..., in my zabbix server with the "ZabbixApiAbstract.class.php" file. I can add a host in a hostgroup until the groupid of the hostgroup is higher than 9. When i want to add a host in a hostgroup which have a groupid higher than 9 the api function "getResponse()" return me "API error -32500: No permissions to referred object or it does not exist! " even if the hostgroup exist
