I am unable to see or edit events that are in the past. They will show in the Select Event dropdown but will not show in the Event Management list so I can change them. This is especially frustrating when some of the events still show up on the front end to allow registrations and I cannot edit or remove them.
Make sure your user account isn't in multiple groups. I had this issue when a user was in both SuperUser and Registered. Registered users were not allowed to edit events, so this user couldn't edit. Yes, it should take the SuperUser permissions, but it didn't.
