Drupal 7 libraries not setting up
I use Pantheon to host my Drupal 7.56 site and I've tried using h5p to create a presentation, but when I tried adding a content and press install for CoursePresentation, I got an error Course Presentation could not be installed. Contact your administrator and 2 errors in console Failed to load resource: the server responded with a status of 503 () in H5P.CoursePresentation and Installation error SyntaxError: Unexpected token < in JSON at position 7 in h5p-hub-client.js?oyt6ov:8.
