Environment - Adapt Authoring Tool running on a Windows 10 Laptop.
I have had an issue with my course I created.
Initially I had the background scroller in the course, and this caused an issue when we went from course page to course page, in the sense it displayed everything but the actual content. I discovered that using the "Parallax Background Scroller".
The issue is I turned off the original one - putting it to false in the places it appeared and made the Parallax one as True and all set to Parallax.
The issue I have is when I try to preview the course, I get nothing appearing on screen. This is now really urgent as it should have been delivered and these things are causing issues. Preview worked previously.
Is there a known bug? Is there a debugging tool that I can see where issues may be?
