Installation and server related problems

I have an interactive presentation that seems to be corrupt. I can access all of my other files just fine but I really need to access this one. It took a good 20 hours to create. I don't have h5p installed in my server.

Any suggestions? Is there any way for users to get access to a previous version of a file?

Hey h5p-Team!

I have two comprehension questions about Interactive Video & CORS:

1. I read in another forum topic about the Interactive Video needing CORS allowed, so subtitles can work. Is CORS needed for other features as well and if not: is there / will there be an option to shut off subtitles and don't use CORS?

We are encountering a problem where when we attempt to restore a course with h5p activities from our Moodle 3.4 environment to our Moodle 3.6 environment an error is encountered error/unknown_context_mapping.  The course can be be restored successfully by skipping the h5p activities.
