background won't appear in boxed layout

Hi,

I have chosen to have a boxed layout but when I pick a color and a texture they will appear on the demo in enfold admin but not on my site why?

How can I fix that?
My site is on maintenance mode so there is no need to ask me for url.

exemple:

Kind regards,
