Mobile: header-image missing and menu is blue

Hello,
we use the Goran theme.
Except for the start page (www.nowato.com), the design on mobiles (Samsung S7 and others) does not take the Goran-design over. The Header is missing and the main color is blue. The logo is missing.
I made an update on Edin last week but I am not sure if it could be the reason for that.
After spending a few hours with this, with no success, I would be very thankfull for any advice.
