Ok, I have done some more testing and it looks like the problem is with your wagmp_maps.js file in the google_javascript folder. In the files that you sent yours looks like this:
window.onunload = function() {
GUnload();
}
/*wagmp_onload*/
if(window.wagmp_map_1) wagmp_map_1();
The reason the map is not loading is because your map is wagmp_map_5. It looks like you copied this file in from another site, or the page with the map on it was copied from another site. You will need to update this file so that code inside looks like this:
window.onunload = function() {
GUnload();
}
/*wagmp_onload*/
if(window.wagmp_map_1) wagmp_map_1();
if(window.wagmp_map_5) wagmp_map_5();
In order for the map to work correctly it should be created in the site you are using it in. When you create a new map this file should be updated to include the additional line of code for the new map.
