Drag and Drop Question - Stuck on Loading semantics, please wait...
I just installed H5P and trying out the drag and drop questions. The demo from h5p.org loaded ok. However when I go in to create one of my own - I select Drag and Drop Question and "Loading semantics, please wait..." appears. and from there nothing happens.
Even if I go into the example that was downloaded, and click edit.. it comes up with "Loading semantics, please wait..." and just stays there.
I am running Wordpress 3.9.1. Any suggestions on troubleshooting the issue?
Thanks in advance
