Thank you for your reply! I followed your link to look for a contact form, but all that “Contact Support” page shows me is a list of links to community forums.
So I was going to give you a link to my site so you could have a look, but first I turned “Let visitors use a WordPress.com or Facebook account to comment” back on and tried leaving myself a comment to make sure the problem still occurs …
… and, of course, now everything works fine. So it looks like that was a temporary glitch?
Thank you again for your offer to help. If the problem comes up again, I’ll let you know.
Thank you! I’ve submitted some changes.
Looks like you fixed this in git; it just hasn’t made it to a release yet.
