I use MMM-Carousel with a long list of other modules. When I did the update to 2.18 goes black screen when I add modules. Plus lost my laptop that all my backups where on. HDD failure… I am really just wanting to get it back the way it was…
Usually I can reload MagicMirror 2.16 and just copy my modules folder into the new install and everything works.
As of right now I have MMM-Carousel working with default calendar, iFrame, MagicMirror-backup-restore, MMM-DarkSkyForecast, MMM-Snow,
and MMM-SugarValue. If I try to install other modules, I get a black screen.
I have tried many different ones and each time I have to: rm -rf MagicMirror and then reinstall with Sams auto installer. I am in the mid twenties, trying to add different modules…

This is my normal list of working modules…
