I've cancelled a Facebook event on a page I administer -- I was expecting the event to remain in the events page, but marked Cancelled, but it appears to have been completely removed. Is there some option similar to "View Past Events" for cancelled events?
if you can find the numeric ID of the event, (maybe its in a previous email notification you have recieved about the event) you could look up the events details via the Facebook API
the event ID is the number in the URL after "/events/" for example in the following event URL https://www.facebook.com/events/123456789/
the event ID would be 123456789 so copy that ID then go to the following page,
and replace any text in the text box next to the submit button with the Event ID,
You should then be able to see the event's details there
