Hi, no idea whether this is the right Issue to post my problem. I made a new installation both Raspbian and MagicMirror. The latter with your script. Unfortunately I cannot start and stop MM via the commands "pm2 stop mm", "pm2 start mm". I tried to install pm2 manually again but no success.

if you used my script, the name is not mm

pm2 status

will show you the manged apps

can u post the ~/install.log
