Thank you, Doitsu.

I had ampersands in the middle of categories (eg Action & Adventure) in the BISAC categories. I hadn't thought they would affect the validation, but when I replaced them with & the two persistent errors went away (thank you).

But in their place I had a long, long list of things the Validator didn't like in my pages, and in the opf file and the nav.html file. A huge list. None of it had turned up in the Validator reports before.

I worked on the page errors, thinking I could resolve those more easily, but each time I fixed one, it would find something else wrong. I had to add a viewport setting, then I had to add a height and width to it. When I'd done that it said I had a fatal error on every page because the <head> tag wasn't closed with a </head> tag ... But it was there. Every page had a </head> tag at the end of the <head> section.

I downloaded Sigil then, and opened the EPUB with that as you'd suggested. Sigil offered to fix errors and I chose yes. Then I saved that version and tried it in the epub validator. It returned a much shorter list of errors in the opf and nav.html files (no fatal errors listed).

In the meantime I have no Idea if the other changes I made (viewport) were even necessary.
