I imported a course content in a new set up course. A few themes in the old course were set up "invisible."
Now I tried to make the themes in the new course visible, and it doesn't work (It doesnt Show me the Option)
Is it in generell not possible to make themes ( that have been invisible in the old course ) visible?
Before importing course material, do I have to makes all themes visible?
Thank you very much in advance.
