For some reason, this is stopped working, and now displays Unknown "nil" back-end: Aborting export In the *Messages* buffer, I see org-export-barf-if-invalid-backend: Unknown "nil" back-end: Aborting export So how is the back-end supposed to be defined? (And why might it have broken?) I haven't not made any related changes in a *long* time. Thank you. -pd
