Ok, I got it working again. Since I am a beginner this might be a little bit unusual but that’s what I did:
1.) in my modules folder I renamed the existing folder to “mvgmunich_alt”
2.) then I did a new install as described here in step 1 and step 2: https://github.com/mrVragec/MMM-mvgmunich
3.) I skipped step 3 but I copied the whole configuration block from step 4 to my config.js
4.) Then I put in my information like haltestelle, etc. and it worked again
5.) I discovered that the ignoreStations part did not work but after putting in the name exactly like stated in https://www.mvg.de/dienste/abfahrtszeiten.html, for example “Moosach Bf. U S” everything was like before.
Hope that helps!
