@jani-karna thanks, can u tell me where u got the update instructions?
 - 
@sdetweil
from here:https://github.com/MichMich/MagicMirror#updating-you-magicmirrorand followed the instructions in “updating”-section. I first did the “test” update and then after no problems used the “apply” as instructed there.
It didn’t mention “npm install” there. - 
@jani-karna ok, the script WOULD have done the update, but it failed…
can u send me the MagicMirror/installers/upgrade.log?
same id as here on gmail…
thanks

@sdetweil should be on its way now.

@sdetweil is there any easy way of backing up any modified files, configs or .css files. The upgrade messed up a lot and even when I thought I had everything backed up as files there were a lot of changes I had to manually fix afterwards.
The upgrade process mentioned custom.css to be saved and restored after but it didn’t.
