Installation and server related problems

Hi there,

Please advise on the below error (which I think is happening because I first did it on our Moodle test environment): 

This happens when I try to 'Register an account on the H5P Hub here'. Via the 'Plugins overview' > [next to] mod_hvp, click 'Settings' > ...mod/hvp/content_hub_registration.php > input relevant information in mandatory fields

We used H5P Interactive Content so far, very intensively. We had created a lot of H5P contents with it. After we updated to Moodle 5 in order to obtain important security patches, the plugin isn't compatible anymore and also all our so far created contents are just gone from our courses.

Will we be able to use H5P Interactive Content plugin with Moodle 5 and if yes, when?

How can we regain access to our lost contents?

Are you going to be updating and correcting the XSS problem in the plugin? I've just lost a ton of h5ps because of this major security issue.

Thanks!

Holly
