Ciao Manuel,

Or set it by Custom CSS, for example:

#sp-header {height: 90px; }

Template Options > Custom Code > Custom CSS

Yes, this worked, thanks a lot. I have only changed it on the page custom.css Let's see if I can find the source of this weird global change... Thanks again

You don't need

#sp-header {
    height: 69px;
}

Header height setting 60px fix menu item a/span line-height to normal 60px. That was the cause of the problem since it was line-height: 69;.

But Header height itself should be auto from template.css
