We've introduced a change to how viewing an unpublished an event works.
Sometimes, event organizers share a link to an event, and then decide they want to unpublish the event. Previously, anyone who directly accessed the link of an unpublished event could view it.
We've now changed it so that only administrators of an event can view an unpublished event page. Anyone else visiting it will see a message stating that the page is unpublished, and will not be able to see any of the details about the event.
