Just to follow up on Jukka's excellent advice: passing the MAP name in
the LAYERS parameter in a WMS GetMap request is an undocumented trick to
return a map image of all layers, from MapServer.
I would follow Jukka's advice. I would start with a GetCapabilities
request, make sure no warnings or errors are reported there, then
request each layer by name through a WMS GetMap...that way you can
narrow your problem down to one layer. Once you have that one problem
layer, remove all other layers from your mapfile, then try again. If
same problem occurs, then try to access that shapefile (not loaded into
PostGIS) by a GetMap request - if the raw shapefile works then you might
have a problem with PostGIS and you can focus your attention there.
Hope this helps a little.
