[mapserver-users] Problem rendering multiple layers

mixing the mode=map with a WMS request might be treated differently in
5.0 than 5.6. To be on the safe side, either do a mapserver style
mode=map request without the SERVICE and REQUEST params, or do some
pure wms requests without the mode=map (the second option seems to be
what you are trying to achieve)
i.e.: try
http://10.10.10.105/cgi-bin/mapserv?map=mapdata/ccc.map&LAYERS=county,water&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-122.41859552788569,37.48140447211431,-121.56140447211433,38.33859552788568&WIDTH=450&HEIGHT=
