Reef-Pi - Cannot access UI - Disable Prometheus

[mbartho]

Can anyone tell me how to disable Prometheus via the command line? I was attempting to get it set up and after enabling this option and doing a reload, I am no longer able to access the web interface. I really do not want to have to reload everything.

dang, I'm in the same boat. Looks like the UI is crashing because of an invalid metric name after enabling Prometheus.

the workaround works but now needed every time any feature turned on/off. Just so you have my experience on my test install
