I keep getting a "Page not found" error when I click on months or years (via scroll dropdown) of events that are not yet created. The messages say, for example, "The requested URL /events/2011-05 was not found on this server." Obviously, I assume it has to do with something in regards to the slugs (urls) not yet being created yet. I did not go through and create page urls for every month, of every year, for the past and future decade. Is there a way to simply display a message when the event does not exist for day/month/year that says something like, "There is not an event for this day. Go back to events."??
