More troubleshooting: I deleted the config.js and it loaded and said I needed to load a config.js file. I loaded the sample one, and it went back ot being a black screen.

@sdetweil when I go into the developer console, it says " devtools was disconnected from the page. Once the page is reloaded, devtools will automatically reconnect."

If I x out of that and go to console, it’s empty.

@sdetweil Im sorry, where do i do this at?

@sdetweil I did git pull in the ~/MagicMirror parent directory. That gave me a few errors about changes, so i just did git pull --hard. Then I did npm install. For the other modules, i just did git pull and npm install.

@BKeyport said in MM cant boot, wont boot!:

One other thing you can do is run “npm run config:check” in the magicmirror root directory (~/MagicMirror) - it’ll run through and see if there’s anything that’s slightly out of wack to blank the mirror but not out of wack enough to throw an error. It’s saved me lots of headaches several times.

I am having this same issue. I ran the update and everything was fine except my calendar and the 2 day weather thing, which looks like a known bug. I rebooted and am only getting a black screen with the mouse cursor. I did some digging and ran the npm install on the main magic mirror directory, and the directories for the modules i’m using, and it’s still not working. I tried to do the npm run config:check and it came back with an error saying " > magicmirror@2.11.0 config:check /home/pi/MagicMirror
