I already followed https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror but still not working. I will try a reinstall to see if it fixes anyting

I`m using NextCloud and i figured it out using the following config

           {
                    module: "calendar",
                    header: "username",
                    position: "top_left",
                    config: {
                        calendars: [
                           {
                             symbol: "calendar-check-o ",
                             url: "https://username:app_password@nexctcloud.domain.nl/remote.php/dav/calendars/username/8a757113-03ae-4d7a-a6a1-8db4350eee54_shared_by_username?export"
                            }
                         ]
		}
	},

I got the calander name from the webinterface by clicking on the dots right behind the specific calender.

Note: I am using a dedicated user to login to nextcloud. This user is recieving the “shared” calanders from the actual users. In this way i don`t need to login with my own nextcloud credentials

I reinstalled using the installer and now it is working

bash -c “$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)”

Although autostart is not working (yet)

I just copied config/config.js.sample to config/config.js and got the same messages about

“No helper found for module:”

I tried to setup a RaspberryPi3 with MagicMirror but when i start MagicMirror i only get blankscreens.

No helper found for module: helloworld

This is the only module enabled in the config to rule out any specific module issue
