interactive book

Good afternoon.

I'd like to know if there have been any changes to the Interactive Book model. I've been working on a huge project for my thesis using this model and I've created many "Drag the Words" activities.

However, I've tried to add new activities and noticed many of the Interactive Book contents have been removed, such as Multiple Choice, Drag the Words and Drag and Drop...

Has anything changed? Is it a problem on my end? Is it temporary? 

Thanks in advance!

We migrated from Wordpress.com to Wordpress.org, the owner of the content downloaded the content via moodle I belive using the reuse function. He now has all of the content sitting in a folder.

I have now setup a wordpress.org using AWS Lighstail for hosting. Everything is running brilliantly and I have downloaded the sample h5p book and uploaded with no issues. However, when I try and upload one of the owners files it says it uploads and then produces an error 500 (all attached).

In moodle 4.2 interactive book flickering while opening if where are more content from standart window size, can be problem with JS-resizer.

This problem apears in chrome, edge, brave and some times in firefox

I append file with example. It is translated to german.
