I've made an application that displays shapes on Google background. It works ok on my development machine but when I it on the web server I do see the map for a second but then it covered with a solid, pink "panel". The problem is not in the Google Maps API Key (I replaced it for my domain) because when I display just the Google background itself - then it's all ok. Below I'm pasting a fragment of the code I use.
LayerOverlay shapeOverlaySiatka = new LayerOverlay("Siatka", false, TileType.SingleTile);
shapeOverlaySiatka.Layers.Add("PolaAtlasowe", shapePolaPL);
shapeOverlaySiatka.Layers.Add("Punkty", shapePunktySQL);
shapeOverlaySiatka.TransitionEffect = TransitionEffect.None;
Map1.CustomOverlays.Add(shapeOverlaySiatka);
Map1.CustomOverlays.Add(google);
Thanks,
Wiesiek
