Some webpages don't load

[teachermuriel]

My website URL is: http://teachermuriel.epizy.com

I’m having problems with pages like this:
http://teachermuriel.epizy.com/grammar-presentations-4/ing_ed/html5.html

What I’m seeing is: the page is loading forever or simply remains grey
I have many more pages like this that don’t work although they used to work on my previous website. One similar page does work: http://teachermuriel.epizy.com/grammar-presentations-3/comparison/html5.html

I uploaded through filezilla. The problem is not dependent on web browser.
I’m baffled because the one page does work and all others don’t. Can anyone help?

On the broken page, I see these errors in my browser’s Javascript console:

SyntaxError: expected expression, got '*'
ReferenceError: PresentationPlayer is not defined

I don’t know exactly what causes this, but I can tell it’s probably a bug or a configuration error with the slide show on that particular page.

I removed this specific folder and re-uploaded all the files using the “upload folder” this time, but unfortunately no luck. The page still won’t load. It’s the exact same folder as on my old website and it contains the same files:
The exercises were created with a ppt plugin.

player.js file is corrupted - it contains some non-normal characters
scroll here and see http://teachermuriel.epizy.com/grammar-presentations-4/ing_ed/data/player.js
(on cca 10 places is broken)

I hope you have a saved project/template for that test - so generate all files again with iSpring Suite
