Hi Medhat,

I checked the configuration and it looked ok, I was also able to restore it on a test PBX and access the Office Hours without the error 500.

I suspect there is something wrong elsewhere on this system so I would suggest to proceed with a ticket via Support for further investigation.

Look this all option which may be related to calender I have checked

As JohnS restore your config without any problem, perhaps this is quicker, than a ticket support, to try a pbx reinstall like i said previously

Thanks Guys,

Is there any option to repair 3CX?

A reinstall may take no more than a quater backup time included
