[mapserver-users] MapServer 3.5 & Postgis

Wed May 15 11:23:16 EDT 2002

The problem is with the 'STATUS' line. It is counter-intuitive, but
setting the STATUS to ON does not actually turn on the layer. It just
sets its default state to on, in case you are reading the map object in
Mapscript or something. You have to either set the status to DEFAULT
(good for testing) or explicitly request it in your URL.
