Templates preview and publish black or with black background

All of the site templates I choose look good until I preview them, then they go black--for instance the ones with the two shades of blocks and pictures, I liked the grey one, but it came out black. The other was orange with lighter orangy peach background...it came out with a black background and not the peachy orange.
I will attach a pic frome site builder then from the preview.
