Hello Telerik Team!
I installed clean SF 5.3 on my Windows 7 Ultimate SP1 and met that issue: when I try to open backend (/sitefinity) - the project crashes and gives me exception (see attached screenshot). I have UTC+03:00 time zone and tried to change it in my system, but it didn't help. Also I tried to install SF 5.3 on another PC with Windows 7 Professional and got the same result.
Also I have SF 5.0 project that I recently upgraded to SF 5.3 - frontend totally working but backend gives the same exception.
Please advice if there is any simple solution for my problem, or let me know if you need more details about it.
The issue may occur at the Azure VM where the site is running the error thrown from the method ConvertFrom tries to calculate the time for the current time zone configured on the Azure VM. In this case the system can`t retrieve the time zone configured on the Virtual machine where the site is running.
If you have configured RDP to the Azure instances login to the instance and configure the time zone settings on the VM and then check if they can be retrieved from Sitefinity after (for example change the time zone on the server).
