I’ll admit this sounds crazy, but here’s what I see:
First, if I disable the page header on the standard page editor, it doesn’t go away. It does go away, if I actually remove the link in the page header section. OK No problem.
When I go to the Customize>Site Identity section and upload the header (I assume as a Logo?) nothing happens – i.e. no header. No change at all. The image is 960 x 120 if that matters.
I’ve been messing with Generator, if that matters, but not today.
Thanks for your help.
