I thought this was an NDG Flexible Admin issue. But all my Accessories refuse to acknowledge the presence of *modified* member group [Pending 4].
In a fresh install, I modified the base “Pending” member group and turned it into a semi-Admin account; giving it various grades of CP privileges. The purpose was that we wouldn’t need a Pending group. And short of littering the system with unwanted member groups I hijacked it.
This resulted in it not being available as an option (checkbox) across any Accessory I’d install.
