Magic Mirror only shows black screen

 @maddinmirror said in Magic Mirror only shows black screen: After working on the config file for the whole day it suddenly wouldn’t start anymore. Undo you’re changes to the config.js file to the point where it was last working.

- Check your changes with git status. Any changes that you didn’t make on purpose? (Especially check theupdatenotificationmodule Validate them and revert them if needed
- Rename your config _config.js(Or someting…) to force the MagicMirror to load the defaultconfig.js, check if the expected config file error appears

 Your MM has been missing modules/node_modules/node_helper/index.js. (I don’t know why)
 You can copy https://github.com/MichMich/MagicMirror/blob/master/modules/node_modules/node_helper/index.js then paste it as new file and save it toMagicMirror/modules/node_modules/node_helper/index.js.Or reinstall MM.

 @Sean u meant node_helper/index.js 
 Right?
- 
 @sdetweil yes. Sorry. my mistypo. 
- 
 So the correct path is MagicMirror/node_modules/node_helper/index.js
- 
 @sdetweil corrected. Thanks. :D 
- 
 @Sean Thank you so much. That worked and it’s running again! 
- 
 @maddinmirror Glad you managed to get it working again. Can you mark the post as Solved if you are happy with the solution?
