Visualization issues in header, content and footer

Hi there,

I built my website with twenty twenty two on my local server. After moving it to my domain, it doesn’t work properly. while everything’s looks fine in the editing mode nothing works right online.

Examples:
Navigation is shown as a list in the right corner
Overlay Menu doesn’t work. I only wanted to show it on mobile devices but if I choose that setup you can see the icons on Desktop also
Image Galary 3 columns is shown a 1 column
Element media+text doesn’t follow the rules for mobile devices (stacking)

It would be very nice if you could help me with this problem and find the resolution ??

Let me know if you need more info
Thx
Carmen
