Under the 'WordPress Location Archives' setting it says:
Location custom post types can have archives, just like normal WordPress posts. If enabled, should you visit your base slug url http://beat-magazine.co.uk/wp/events/ and you will see an post-formatted archive of previous locations
Is that the correct URL? It is the same URL given elsewhere for the events archive and it doesn't list the locations.
Also, what does the word 'previous' mean in the context of locations?
