Installation and server related problems

I'v no problem on my own local server with H5P on Drupal 8, it works perfectly. But with the same installation on the shared Hosting (Hostinger) I work with, I can use all H5P Content except Branching Scenario, Column, Course Presentation, Image Pairing, Interactive Book. I have changed any PHP parameters I can change (because of the limitation of Sharing Hosting) :

Hi everybody, 

I keep almost randomly losing changes to my presentation when editing a presentation in WordPress. This often happens when I cloned a slide but also when simply making changes to content types used on the presentation. Sometimes it does happen, sometimes saving by using the Update Button works. I have looked through the forum, there are reports of issues like that in 2017 but I can't find anything recent

Dear community,
I have installed the H5P plugin on Moodle 3.5. But H5P cannot install the content types via api Hub. The following error message appears:

Failed to download the requested H5P.
