Thanks, John.
“If you’ve changed themes and you are still seeing ACF fields (do you mean options pages), then whatever is being done could be done in a plugin.”
No, these are ACF taxonomy links (and “empty” custom post types fly-outs) in the main WP Admin menu (down the left column of WP Admin) which have nothing to do with the new site theme or plugins. I can see from the “live” site (using ACF) what these all relate to, but there aren’t needed in the new theme site.
I understand from reading the forum that it can be very problematic removing un used ACF fields. I’d be very wary about removing anything directing in the DB. :-0 🙂
