Storyline 3.18.28642.0 publishing breaks tincan tracking -- forbidden

are there error message in the browser console?

is the html and the iframe in the same domain?

The only console error I get is the one I mentioned before:

actionator::exeJavaScript - track_completion is not defined

It says it comes from bootstrapper.min.js:2:149179

Not sure what you mean by "is the html and the iframe in the same domain".  I imagine they are -- I don't do anything fancy here -- just call a javascript module that works in every other browser.

add some debug code "console.log(...)"

function injecttracking() {
  console.log( "injecttracking" );

  var head = this.contentDocument.getElementsByTagName("head")[0];
  var scr = this.contentDocument.createElement('script');
  scr.type = 'text/javascript';
  scr.src = '/js/track.js';

  head.appendChild(scr);

  console.log( "head", head );
  console.log( "scr", scr );
}

add in the track.js before the first line and after the last line also a console.log("...") command

first try it with chrome, if it's ok then try it with firefox

make screenshots from the browser console with all log messages

It's all very strange.  When I use Chrome, it works fine.  My initial injecttracking console statements show up at the beginning.  When it's time to call track_completion, I see a quick ... and then the console messages disappear.

When I do this in firefox, I never see any debug statements.  There are some errors, as shown in the attachment, but the module starts up and runs fine.  It just doesn't put out debug statements, and it always gets the same error -- actionator::exeJavaScript - track_completion is not defined

i need the COMPLETE console output with the "console.log" commands in chrome and the same version in firefox, then maybe i can see what happens

When I run firefox, I never see the debug statements, which seems to indicate that injecttracking is not even being called.  I never see track_completion being called -- just that error message -- actionator::exeJavaScript - track_completion is not defined.  When I get to my NEXT screen to continue, it just hangs.  However, if I come back in to our training, it looks like it actually worked -- it shows that the module was completed.

As for Chrome, I do see the injecttracking debug statements, and have attached those.  However, when it gets to track_completion, it works, but the debug just shows 3 quick dots and goes away.  I would also notice a console error on this line (the function after track_completion) -- 

$(function () {
// disable caching of GET requests in IE
$.ajaxSetup({ cache: false });
});

where it said it didn't recognize $.  However, when I took that out, the behavior didn't change for either browser.

I don't know why Firefox is different -- Edge and Chrome work fine.

One other note -- I did see an Articulate article that says:  Don't include <script type="text/javascript"> in your code

Our injecttracking does have <script type="text/javascript"> and </script> around it, but taking that out just causes our source to show up in a window behind the training.  This happens in all browsers and doesn't make any difference as far as behavior is concerned.

if "$" is not recognized, jQuery is not loaded

since storyline 3.36.21213.0 jQuery is not integrated anymore

why are you use "http" and not "https" for import your files?

https://developer.mozilla.org/en-US/docs/Web/Security/Mixed_content

Starting in Firefox 23, mixed active content is blocked by default 

try change all "http" to "https"

Where are you seeing http?
