[mapserver-users] Mapserver can't read mapfile

[Jeff McKenna]

Hi sorry long thread and I bet this has already been said, but here were
my thoughts when I read your problems:

- always test your mapfile at the commandline first, using the shp2img
utility (http://mapserver.org/utilities/shp2img.html).  Once your layers
look find there in the generated map image then move to your application

- if using MapServer CGI (mode=map), a blank map often means you are not
specifically telling MapServer to turn on layers; try adding &LAYERS=all

- or setting each of your layer's STATUS values to DEFAULT might work
(but this can cause lots of trouble later, so this is not often recommended)
