[mapserver-users] Map is OK with shp2img but blank with CGI

[Rahkonen Jukka]

Hi,

It would be a great help if you could send the whole mapfile, otherwise we must be guessing.
Still, here is my guess that is not related to mapfile but to where it is. Your mapfile is now in d: root directory. It may well be that Apache does not have a permission to use that.  Move your mapfile somewhere under ms4w, for example to ms4w\apps.
