First, some of the pages were causing critical errors, but an upgrade to ACF Pro has solved that.
So, the question is this…
With ACF Extended active, the situation on a taxonomy index (edit-[taxonomy].php) is different… The full in-page form you normally get is demoted to a form that unveils itself when you click the “Add New [Term]” button.
I can’t find a setting to override this and turn it back to the WordPress default (though it does ring a bell). Though deactivating ACF Extended does the trick, I may have some field groups that depend on it, I can’t remember.
I don’t know if ACF Extended really has a single settings page of its own.
Is this revertible to default, or is ACF Extended always going to do it this way?
