Container Background image Issue


When I add a container to change the background image, then my page is full blank (in my editor layout it shows well)
I have this :

It shows :

That looks like you have an empty collection.

Are you signed into the App as the same user you are viewing as in the builder?

I don’t sign

Can you show me a screen shot of the configuration of the Collection, as well as the source data table?

I don’t know what I change, but it works now…

Thank you
