Hello folks;
I have problem with dashboard. I enter login and password, page is loading
for a while (about 10s) and then I receive an Server Error.
I managed to log in once just after dashboard installation, after that I
have been doing some admin stuff with Nova only and from that moment
dashboard does not work properly.
Logs below:
