Can't create trigger in template

[Jaroslav_Safranek]

Hi,

I'am using Zabbix in ver. 2.0.6 on MySQL.
I have problems when i try make new trigger for my template Ping.
Normaly I click on New trigger and type Name and Expressinon (first screen), but when Save no result, only this second screen. Trigger isn't saved.
Same error is when I need change expressinon on normaly function trigger.
On host I can trigger change or create normaly.
Template Ping I was create about half year in past and it worked normaly.
Is there any error on Zabbix frontend in this point?

Thanks for replies.
