Yes. I’ve heard the same thing, which is why I’ve tried that several times, and why it’s in the list above.

Not to mention the fact that “not uploaded properly” isn’t really a thing. You either upload something or you don’t. The likelihood that one or two files get repeatedly corrupted through a simple and successful FTP process are pretty slim.

Regardless, I fixed the problem. I had the idea to go check for Javascript errors on the Edit Post page, and found a number of errors that looked like this: Failed to load: http://letsreview.frenches.com/wp-admin/http:/wp-includes/js/tinymce/themes/advanced/editor_template.js

Notice that ‘http:’ in the middle of the url? That looked familiar to me, so I went to the General Settings tab, and found that same ‘http:’ in the ‘WordPress Address (URL)’ box – all by itself. I didn’t put that there, so it was either part of the default installation, or something my host did in their automated installation routine. Changing that to my actual URL fixed the problem, so either way, the problem ended up being a value in the database. I could have re-uploaded files until the cows came home, and it never would have done any good. And why that data-field only affected the Visual Editor is beyond me.

So if anyone else comes across this problem, there’s one more thing to check.
