Access Sonarr WebUI stuck at 4 dots loading

[brunosso]

I have this problem! I try to restore from a backup but nothing changed…

This is the log (there is no error!) http://pastebin.com/k2eW2YPV

This is a scree on the loaded page and the develop bar with two warnings

How can i try?

This is my mono version:

Which version of Sonarr?
Which OS?
Have you tried reinstalling Sonarr?

Sonarr Version 2.0.0.4427
Raspbian Jessie

I try to purge nzbdrone and reinstall it and it works again with a previous backup

Thanks!!!
