Hello:
I have updated zabbix version from 1.8.5 to 2.4.6
When I try to link link a tamplate to a host I recive the following message:

Template cannot be linked to another template more than once even through other templates.

This message didn´t appear in 1.8.5 version.

Is neccesary to do some changes in the template?.

Let me know if you want more information.

Best regards
