Bugs in content types

Hi there,

instead of getting a H5P-Downlaod file, users on my Wordpress-website just getting some strange code.
https://www.schooltools.at/schooltools-h5p/musik-memory-2/

It also doesn't work with Edge, but it seems to work in Firefox.
The error appears in FE as well as in BE..

Any ideas?

Thank you in advance.

In 2022, I created a relatively complex and multi-part course as an ‘interactive book’ that I would now like to offer again. When updating some content, I received the following error message when saving: ‘count(): Argument #1 ($value) must be of type Countable|array, null given’.

We use H5P with WPLMS. We love the 'course presentation' module. We add these contents as a quiz so that the user results are saved. 

However, the last slide (summary slide) only appears briefly and then disappears. This prevents students from looking back or starting over.
