I am trying to generate a course presentation type in WordPress
1. Having failed to create one on a site with a security certificate, I moved to an insecure site.
2. On my test site I can create the object but no slides and can see the following error messages in Chrome:
JQMIGRATE: Migrate is installed, version 1.4.1
jquery.js?ver=1.13.1:2 Allow attribute will take precedence over 'allowfullscreen'.
attr @ jquery.js?ver=1.13.1:2
