Well .. I tested it here, and it seems to work. 2 things though:
– I first found out the locations update didn’t happen anymore in the new-event window: has been fixed in trunk
– then I saw something weird: in the edit event window: google found the location, but after entering “prague” it suddenly showed nothing: it seemed to me one of the google servers had problems …
So I would say: try again by editing a letter (add/remove a space) in the location info, save and see what is the result. In the mysql database (table wp_dbem_locations), I have this as the latitude/longitude coordinates for this location (these are the ones used when an event is shown but not when editing it, then these are fetched from google servers):
latitude: 50.0876
longitude: 14.4282
Also: you can always try the trunk version, and see if it happens then:
