I've been using Geopress for awhile and have noticed that while the map 'box' and google nav buttons and credit is showing up at post bottom, it is now blank other than that. Here's an example: Community Event Page Detail
In the edit window, the map correctly shows the location where the event is taking place, but when the saved post is viewed, the map area is blank except for the border and navigation, without even streets. The named location has been saved and shows up in the location list fine.
I can't remember which plugins I've added since geopress. The only ones I know of are the 'disable revisions and autosaves' plugin, and the remove revisions plugin which I've now deactivated. I've also upgraded wordpress to the latest version and this site shares it's wordpress database with another wordpress site on the same host.
