I just posted on line a single CE4 Stage page in order to show a slideshow to a friend. Nothing special, no navigation, no nothing save the slideshow.
But, when I try to access the slideshow, I get a Backlight error message. But there is no Backlight installation at this address.
What's going on here?
Backlight is installed on that site:
double check your set up. I don't even see anything in a direct url to the photos/ or thumbnails/ folder of that page
