course page empty

And: i have several problems with lessons and courses. Adding a new lessen, the curriculum is not visible, so the lesson cannot be assigned.
Adding a course, I can name section 1, but I cannot add any lesson or quiz because nothing more is visible. No + to add…

Hi,

Do you try switching to another theme or disabling each plugin on your site to check? I think have a conflict so JS can’t work well.

Thanks

Hi Brian,
I installed LearnPress on a new website 1: https://leatherbagsacademy.com/courses/
ánd on a subdomain 2: https://leatherbagsacademy.marablu.com/courses/
Only installed Learnpress, Divi and 3 other plugins on both exactly the same.

The all courses pg work on both.
But: the link to the specific course pg on website 1 is empty: https://leatherbagsacademy.com/leatherbagsacademy-cursussen/sample-course/
and on subdomain 2 I can see the individual course: https://leatherbagsacademy.marablu.com/leatherbagsacademy-cursussen/voorbeeld-cursus/

What could possibly be wrong? All the layouts etc I imported exactly the same…
