Bugs in content types

I have developed an interactive video which is embedded in a Moodle HTML page. I can view it successfully in Chrome on both a Mac and a PC. However in Safari on a Mac, and Firefox and IE on a PC I am told that Content is Unavailable.  

Can anyone throw some light on what is happening here.

Hi,

When I try to save a Quiz Question Set when working on H5P's website, the window keeps saying 'title field is required' even though it is filled in. Upon trying to save, I get this:

The website encountered an unexpected error. Please try again later.

Hi,

I have the following problem when I try to upload a file herop to my Moodle instance. The Moodle version I have is version 3.1.1, and the version of the H5P module that has been installed is version 1.0 (2017060600).

The error that gives is the one that I attached in the incident. Do I have to upgrade to the latest version, version 1.3, the H5P module for Moodle?

Thank you in advanced
