Add guest after public event registration closes

Open Events → Events → select your event → Registrations.

Open the existing registration in event administration and use its administrative Edit Registration/Add Guest workflow, select the appropriate ticket or package, complete the guest fields and save/review any price/payment change. This requires Basic Events Admin, Advanced Events Admin, Events Superadmin, or Superadmin, access to the event, and the enabled backend-registration capability. Public closure is different from administrator editing, but capacity, ticket/package rules and event state still apply. Do not reopen public registration or create a duplicate registration merely to add a guest; ask support if the authorized control is unavailable.

Change staff access

A Superadmin or Events Superadmin can open Events → Administrators → select the person → Role(s), assign the appropriate role using Add Another → Update Role(s), and check Events Access. The role’s individual capabilities are fixed.
