I'm using 6.1.1 (build fc853b) – May 31, 2017 on Ubuntu Server 16.04. Until yesterday, everything was working smoothly, but today, Settings page is blank. I can not see anything unusual in the log. Any help/advice?
Problem:

EDIT:
Apparently, the problem is caused by non-secure http content within settings page. I'm using nginx + certbot to redirect incoming connections to my subsonic (https from outside redirected to a standard installation without enabling https in the local network). I'd appreciate any advice here. Disabling protection for mixed content in Firefox "works", but is not ideal.
