Done :)

First: you did not set event start and end date for your events, but you have had sorting by event date start selected (which is default). There were no dates so the query returned no results, for admin and page not found for the front-end. (by the way I think we’ll ned to change that default behaviour). If you enter the date it will be ok. (you have even an error notice that those fileds are not set)

Second: the editor – you just disabled it in plugin settings (it’s enabled by default)
