Problem importing the demo content

Hello,
we’ve a problem with demo content import: the images weren’t show in product mode, but if I enable the Visual Composer, I’m able to see it
Look attached screenshot
I’ve also tried with different server, but the problem persist. Could you help me?
I’ve re-installed wordpress from zero and the problem is still here.
Thanks
