Installation and server related problems

Hi! I installed H5P on my WordPress site. Now I have a timeline (https://weknow-studienwerkstatt.de/test-h5p), that does not show up, when I embed the code in another site and watch it via IE11. With Firefox and Chrome it is no problem, but IE11 is the required browser for the learning application, where it is posted.

How can I make the timeline visible in IE11?

Thanks for your help. :-)

I have a strange error, with H5P, and after much, much, much research, I stil don't have an answer...
we're using Moodle 3.5 as a platform, but... upgrading to 3.6/3.7/3.8 did NOT solve the issue unfortunately.

Reaching out to the community for the much appreciated help!

what's the issue(s):

1: interactive video not (allways) playing:

Hi,

New to H5P. I have installed a fresh Wordpress installation to test out H5P and have installed and activated the plugin. I have then gone to "Add New" H5P content but the H5P Hub never loads.

If I click on the "Create" button on the right hand side, an error comes up which says "Invalid Libraries". If I go to the libraries sub menu, nothing seems amiss in here although no specific libraries show up.

The "Use H5P Hub" is enabled in the H5P settings.

I am using Chrome as my browser and running Wordpress 5.3.2. Screenshots attached.

Thanks

Courtney
