Answer by Christoffer for After upgrading to google maps api 3.17 all fails

The problem is that place under marker > options has become a used key by the google api.

Changed place to myplace and you are up and running again:

marker: {
        options: {
            icon:
                new google.maps.MarkerImage('/media/img/map_markers/map_marker_' + classname + '.png',
                    new google.maps.Size(37, 31),
                    new google.maps.Point(0,0),
                    new google.maps.Point(14, 31),
                    new google.maps.Size(37, 31)
                ),
            myplace: place,
            draggable:true
        },
