We seem to be having an issue with the Google Maps API in EventPress. It was working great and I am not sure if it quit working when we upgraded EventPress or what. I disabled all the plugins just to see (except buddypress, buddypress custom posts and eventpress) and still have the same issue.
Here is a page where it is not working: http://220.127.116.11/events/bridget-riley-paintings-and-related-work-4/
If you run the firebug console, you will notice that the google maps api request returns 404 due to a bad request. Any ideas what needs to happen / where to look to fix this?
