Unsupported operand types

Mon Jun 20 08:34:00 PDT 2005

See if you install has shp2img.exe and run

shp2img.exe -m /path/to/mapfile -o test.png

and see if it reports any errors? you can also load test.png into a 
browser to see if it generated an image. This will tell you if the 
mapfile and mapserver are working.

If these work, then the problem is probably issues with paths, 
permissions or php code.
