Installation and server related problems

Hello! I just installed the plugin on two different WP installations on Siteground. 

I can't use the plugin at all: I can't connect to he hubspot and, when I try to upload a h5p file, I get the message: "Invalid library".

On the "libraries"  section, I get no libraries installed at all. I uploaded the attaced h5p file and installed some libraries, but still my plugin doesn't work at all.

Find attached the console error in a screenshot.

Is there any way you could help me? This plugin will definetely be useful for my English School. Thanks!

Hello again,

Hope this message finds you well, and thank you for your continued support, and expertize.

Today I’m requesting your help with getting H5P content types running on my PRODUCTION server.  I’ve been evaluating H5P on my DEVELOPMENT server.  I had a little difficulty installing the content types on the DEVELOPMENT server, during the process I would receive errors, but after waiting 30 minutes or so the content types would show up under the H5P hub list, and function without error.  Kind of strange.

I use Drupal. When I want to create a collage I can't even upload a small picture. Loading screen keeps turning. All my folder permissions are default. Thanks in advance.
