Solved White space below header only using Chrome

Hello,
when I open my website with Chrome on PC, i see a white space under the header

Which is not showing when i open the website with Fireforx on PC, or with tablet and phone, as you can see below:

I have already tried clearning the browser cache to no avail. I have tweaked the margin/padding options but it's not because of that as suggested by the fact that on Firefox the white space is not showing.

My website URL: https://www.tekproofread.altervista.org

Thank you so much for your help,
best wishes,
Enrico
