Hello,<br><br>After a look, my results are near the same. With  "wms_server_version"  "1.3.0", I got the same error msBuildWMSLayerURL(): WMS connection error. MapServer supports only WMS 1.0.0 to 1.1.1 (please verify the VERSION parameter in the connection string) but when I use wms_server_version 1.1.1, positions between original layer and the one included into mapserver are OK.<br>
