@Vauxdvihl or, from your laptop or pc, you can ssh into the mirror, got to the MagicMirror directory and execute the following for dev mode:

pm2 stop all
npm start dev

See if there are errors coming up in the console.

Is there still no troubleshooting guide around to reference to?

Vauxdvihl

npm start dev

results in

pi@PiMirrorNeu:~ $ npm start dev
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /home/pi/package.json

@Vauxdvihl from the magicmirror folder

all commands suggested are always from the magic mirror folder

Vauxdvihl

Ah ok
Sorry

DevTools was disconnected from the page.
Once the page is reloaded, DevTools will automatically reconnect.

@Vauxdvihl this is still MagicMirror version 2.9?

a guess

do

cd ~/MagicMirror
git checkout modules/node_modules/node_helper/index.js

Vauxdvihl

@sdetweil
Where do i see it?

Nothing happen:

pi@PiMirrorNeu:~/MagicMirror $ git checkout modules/node_modules/node_helper/index.js
pi@PiMirrorNeu:~/MagicMirror $

sdetweil

@Vauxdvihl
and then restart mirror

Vauxdvihl

@sdetweil
Mirror stays black :-(

sdetweil

@Vauxdvihl if you do

cd ~/MagicMirror
npm start

what do you see on the terminal window?

(alt-spacebar, n to minimize MM screen)

Vauxdvihl

pi@PiMirrorNeu:~/MagicMirror $ npm start

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
