OK, One thing i find out now ........ (stupide me

The performance graphs was end working because like we messed around with the timeperiods.cfg in the xi_timeperiod_24x7 there was no time entered and all hosts was out of notification period. I put in the timeperiod 00:00-00:24 from friday to sunday (24x7) and al the graphs are working again.
-------But still no view changes in NagiosXI views-------- And after restarting the Server NagiosXi is only showing a blanc screen. OK saying like this, when i enter the servername alone there come the Welcome Screen with " Access Nagios XI" , but when i enter http://servername/nagiosxi then i get a Blanc screen, where i normaly should get a Login Screen.
