Problems with content in Course Presentation



I run a Moodle plattform and I came across this very puzzling problem:

A Course Presentation one of my authors designed was shown in the Moodle course, but when you click on it, it is not displayed on the next page, that is empty. If you want to work on it, that's possible, but the results cannot be shown.

After some very extensive fiddling, I hit on the fact that "Single Choice Set", "Drag and Drop" and "Drag Text" cause the problem. When I remove them, it runs just fine.

The funny thing: When I do a different  Course Presentation and insert thos content types, it works just fine. However, when I try to copy the one I have there into the problem presentation, it doesn't work there. I have also tried remaking the problem presentation from scratch, all anew. It doesn't work then either.

Has ANYONE ever encountered this? Has anyone any idea what is going wrong here?


All the best,

Hi Julia,

This quite an unusual issue. There is a possiblility that another activity or a specific setting is triggering this since you mentioned that the said activities works on another presentation.
