Certain (non-compliant) WMS servers do not support GetMap requests made in EPSG:4326. One example: http://gis4.vibamt.dk/ecwp/ecw_wms.dll?REQUEST=GetCapabilities&SERVICE=WMS Note the last layer is the only one with a proper SRS set. There are some things that can be done in this case: If we are creating a new map, we could force the new map to have a projection that the WMS supports. If we are adding to an existing map, I am not sure what to do. Maybe change to a CRS that every layer supports, if one could be found. And the ideal case: Raster Reprojection!
