Installation and server related problems

Hi,

Recently updated H5P to 7.x-1.26  on our Drupal install. We had included some custom CSS and JS previously for the Course Presentation in a custom module as:

Question about the possibility of a H5P plugin for Plone, which would imply a Python implementation of the server-side code; this Python module would be  usable for Django, Flask, Turgogears etc. as well.

I am trying to add H5P interactivity to several long videos (30 minutes and longer) which are stored in the cloud and delivered through a CDN. To connect the CDN to WordPress, I need to use W3 Total Cache. But I have found that when I use W3 Total Cache, the H5P shortcodes don't work on my posts.  When I de-activate W3 Total Cache, H5P works fine.  

Can anyone make a suggestion? Is there an alternative to W3 Total Cache? It would be a shame if I need to choose between showing the videos and using H5P interactivity!

Thanks,

Russell
