I am having the same problem. I entered the api key. I got JavaScript console errors before I entered the key, but am getting no console errors or messages now.
On the Location edit page (in the admin UI), I only see text that says “Location not found”. It is the below HTML structure:
div#em-location-map-container
div#em-map-404.em-location-map-404
p Location not found
div#em-map.em-location-map-content
There is a map inside the div#em-map.em-location-map-content. So the map is there, but the address fields are not being fed to the map for some reason. I have tried multiple addresses and get the same result.
On the event page (live site page – /event/event-name), I see “Map Unavailable” in the below HTML structure:
div.entry-content
div
I Map Unavailable
There is no hidden map on this page.
