I have migrated system from zabbix 1.8.10 to 1.9.9 in testing environment.

I have one test template with one simple check item (key: icmpping) and one trigger (expression: sum(#2)=0).

When I want to create host linked to the template error is generated:

ERROR: Cannot add host

Created: Item "ICMP Ping" on "test".
