How to reinstate a cancelled lesson

To reinstate a cancelled lesson, navigate to the course in question from the Didactics menu and click the second icon Lesson Schedule.

Click the green button at the top Maintenance and below "Show maintenance options".

Then click on the icon Undo lesson cancellation on the line of the cancelled lesson to restore it.
