At the capabilities tab, there is this warning: "Any changes to the list of capabilities is permanent." I am logged in as an admin, and it says that even if I am editing a subordinate role or user..
Therefore I am not sure I fully understand the scope of this. Does it mean that changes cannot be reverted?
I mean: I would never mess with my own - admin - capabilities. But when I restrict the capabilities of a subordinate role or user, I can always revert that as an admin from the backend, right...?
