@sdetweil after restarting the whole pi, all the processes in pm2 seem to be running ok, and I can connect over http again.

However there’s still some weird stuff in the logs: 😆

Are these anything that I should worry about?

@sdetweil I manually stopped the bottom three because they were logging so many errors:

I had enabled HTTPS in the config.js but then the mmpm.ui stopped working and started throwing all kinds of errors:

I tried setting useHttps: false but that didn’t appear to revert anything. Is there something special that I have to do to disable HTTPS?

These errors seem to be repeating constantly, unsure if they’re related:

@sdetweil said in updating MMM-mmpm using mmpm web UI and now MagicMirror won't start:

@travishardiman said in updating MMM-mmpm using mmpm web UI and now MagicMirror won't start:

home/pi/MagicMirror/node_modules/systeminformation/lib/index.js

this library is missing systeminformation

cd ~/MagicMirror
npm install systeminformation

Thanks! That fixed it!!

@sdetweil long term update after trying a few things out, the MMM-GoogleMapsTraffic module was the culprit. I started going down the path of trying to update the javascript issues when I discovered that your fork fixed them already. I uninstalled the original and installed yours and I haven’t had the black screen once since.

https://github.com/sdetweil/MMM-GoogleMapsTraffic

Thanks!

@sdetweil ok, I’m starting with the google photos module and see how it goes. Are there any other logs that might be helpful for debugging?

@sdetweil MMM-GoogleMapsTraffic, MMM-MyGarbage, and MMM-GooglePhotos

Well nuts, I thought I was good but it’s black screen again:

The backup didn’t restore my custom.css, mmpm, or some of the configuration files for 2 of my plugins but luckily I had those backed up elsewhere. I’m back up and running again though and so far so good! I’ll post back with logs if I get black screens again. Thanks for your help!

@sdetweil I tried to update the error in the first message with the first line. I posted as new reply in case someone is searching for that.

I just found your scripts here so I’m going to try this today, thanks!

@sdetweil is there an easy way to back-up/restore my current config? I don’t think there’s a way to switch to 32 bit without reinstalling the OS is there?
