@Nneuland magicmirror is just an application. other things might be consuming CPU too. ssh in and run the top command. it will bring up a green of running processes sorted u CPU usage, high to low and it refreshes every few seconds. particularly when the system appears slowed down

@mumblebaj Thank you. The solution was a little misunderstanding, but I figured it out, and now it seems to work.

@thebassfly said in After Update to 2.15, MM ist black.: Cannot find module ‘valid-url’ this library was removed from mm in 2.15 because of security risks. some module u are using is using it, but did not declare it in their package.json file dependencies section do cd MagicMirror npm install valid-url
