Installation and server related problems

Hi Guys - I understand you cannot give instructions on how to implement your great software on every platform that a user deploys - what would really help is a conceptual overview - e.g.

1.Load jquery

2. create a div

3.load content using getUserData or whatever and using jquery put it in that div 

4. Listen for events using whatever function

I have looked at the drupal/wordpress/joomla integration but I dont want to learn these before I understand how H5P is integrated.

I'm a Moodle admin, but new to CMSes like Drupal and Wordpress (I was very pleased to learn that I can pretty much get a working Drupal installation with H5P in one drush command!). 

My question is: ok, I've created some content. Now what?

I can create a page in Moodle, edit the html source, and paste the H5P's embed code, but some of my fellow content developers are less web-technical and it would be nice to not make them deal with HTML directly.

Our Drupal 7 site recently stared displaying 'access denied' errors when displaying a page with H5P content,

A check of the log showed the url causing the error is apparently from an ajax call - a typical url looks like: http://copyoftest7.site.edu/h5p-ajax/content-user-data/15752/state/0 - all of the 'access denied' errors have a 'h5p-ajax/content-user-data/(node)/state/0' pattern.  The content displays without any problem.
