Even this tread is old, but i have an issue with the starting of mm:

Everything worked well, then i installed MMM-CECControl.
I saved my config.js file bevor i entered the module line in there. But not as usual mm didn´t restart. Not even after a reboot of my raspberry.

Also when i start mm with
pm2 start mm
and
pm2 start MagicMirror
nothing happened.

i don´t know what i should do to start my mm as bevore…

@sdetweil
that´s it, MM startet again after the installation
