@calimero said in Bookworm: MM not starting: backup MM folder use your install-script removed module and config-content from backup to new folder also, I have backup/restore scripts that will do that AND allow you to keep different versions, AND save on github NOT on local machine where it might be lost only saves the config, custom.css and a LIST of the modules (where from) on restore, reinstalls all the modules (in case node.js changed during the time between backup and restore) see https://github.com/sdetweil/MagicMirror-backup-restore
