Parallax Support – It's Not Working (for me?)

Hello,

I was wondering if anyone else is having issues with Upfront, specifically Luke + Sarah, not being able to use Parallax Backgrounds? My front page is not able to have a Parallax background. I try to use this and it shows up in the Upfront side, but after saving and viewing in every browser (literally), the Parallax Background does not show up.

Let me know,

Robert S.
