interactive book

Interactive Book contents have been limited

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!

Uploading Interactive Book - 500 (Internal Server Error)

We migrated from to, 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 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).
