Home Assistant isn't loading; nothing being added to my log file

Hello all,

I’m running Home Assistant on HassIO and it’s been running smoothly for a few weeks until last weekend. While I was busy, it seemed to crash while I was busy with other things – no configuration changes, hardware changes, power issues, etc. The OS boots up just fine, I am able to access the log-in page and HASS-Configurator, but the log-in page never fully loads, instead giving me a “Something went wrong” error.

Firefox’s console shows repeated “TypeError: NetworkError when attempting to fetch resource.” errors, and as I mentioned in the title, there isn’t being anything outputted to my log file.

Any ideas on what to look at, or should I just start over? I was still in the middle of configuring things, so I never got backups enabled. Can I just copy/paste files over to a new installation?
