Error in JavaScript for CPXHRLoader.js every time I publish as HTML5 in Captivate 9

I am at my wit's end.  I have successfully published videos with Captivate 9 but they were created in previous versions. So this is the first time that I am creating a tutorial in Captivate 9. I used one of the built-in themes (Chic if it matters) and I have an embedded YouTube video as a web object but other than that, it's completely standard stuff (audio on all slides, no animations, background music on each slide except the one with the YouTube video).

When I publish it as either HTML5 or SWF, it works fine locally. But as soon as I try to upload it to my company's web server or to our Adobe Connect server, it won't work. There is a javascript error with the CPXHRLoader.js. I'll attach the screenshot from Chrome's web developer.

With the SWF version, as long as I click on the .htm file it works fine (and Chrome web developer finds no issues other than that missing file which is okay). But if I click on the index.html file, it won't work. 

My web developer kindly looked at this but he has no idea how to fix it other than there is a problem with the Javascript. 

I know nothing about Javascript. I tried running the code through a couple of "cleaners" online to clean up the code but still no dice.

Anyone with more Javascript experience have any ideas to fix this?

Here is what I have done:

• tried uploading to Adobe Connect 9...both HTML5 and SWF won't play (just spins)  I think even with the SWF it's trying to play the HTML5 index page
• tried cleaning code on https://dirtymarkup.com/ and another place but it didn't fix the issue
• of course I checked if there were updates to Captivate 9; I have the latest patch/version 9.0.2.437
