Check_mk 1.6 version. Problem with timeperiod

Hi,

We just installed the last version of check_mk raw and reviewing the monitoring configuration into parameters of a service or host we see that the options related with timeperiod none of them are defined timeperiod by default. As compared to previous version like 1.5 or 1.4 this options they have a 24x7 timeperiod defined by default.

Is there any procedure to activate this timeperiod by default?

On the other hand, checking the nagios.log we see that this message appear constantly:
“livestatus: Timeperiod cache not updated, there are no timeperiods (yet)”

Thks
