Button to advance to next page in an interactive book not working

Bugs in content types


When a user tries to view an H5P for our course, they aren't able to advance beyond page 2, when they arrive there they cant go back to the first page either. 
I checked the logs and found the following error message:

"Uncaught TypeError: can't access property "Button", H5P.Components is undefined"

It's on Moodle, I think?
So far it has been tested on Desktop.
The browser was Firefox.
I sadly do not know the plugin version, nor the content type version. If that is needed, could someone explain to me how to look that up?

If any more information is needed, please let me know how to provide it and I will.

Thank you very much in advance!

Sounds just like yet another issue caused by not properly bumping the version numbers of content types when the theming feature was released.
