Bugs in content types

I created a single choice set. After doing the choices I get presented the Retry and Show Solution buttons. They seem to be turned around where Retry shows the solutions and the other way around.

Hello everybody

I have the following problem. Since the last update, there are problems with interactive videos on iOs. I'm using drupal 7. Some of the youtube videos, specialy those from us artists are not showing up on iOs. As long as i embed the same videos in a drupal node, it ist working. In h5p video and interactive video it is not working.

We recently upgraded our Moodle installation to version 3.5

Post upgrade we are unable to create H5P content, nor load any previous content.

We see only Loading, please wait with animated circle icon when we try to create new content.

For interactive Video, the brouser console shows following error:

VM2462:4683 Uncaught TypeError: Cannot set property 'Explainer' of undefined
