[sdetweil]

@karsten13 I fixed the title

[svoe88]

@sdetweil
How do I get it done?

[sdetweil]

@svoe88 you missed one of the changes in the workaround. the author needs to fix their module.

For others it doesn’t work too then I copy this code into calendarutils.js

cd ~/MagicMirror/modules/MMM-MyCalendar
