My website was running 2.7.10 of Dtregister. I have a current open event that a member has registered for. Via the front end choosing from the "List available events from registration" when the "attendees" button is pressed his registration is shown. Looking in the back-end for the event the record doesn't show up. I have tried updating the the current version 2.7.12d but the record issue is still there. Any idea how I can clean this up ?
