Hi,
I’m trying to run the default Calendar module on my MagicMirror, but nothing shows up on the screen when I run it. I looked through the logs and I found this message

I’m running MagicMirror server-only on a raspberry pi 2.

This is my config for the calendar module:

             {
                    module: "calendar",
                    header: "US Holidays",
                    position: "top_left",
                    config: {
                            url: 'http://calendarlabs.com/templates/ical/US-Holidays.ics',
                            symbol: 'calendar'
                    }
             },
