[MS4W-Users] Getting blank tiles in google maps

There's a bug in QGIS mapserver export with the Projection
definition. If your target (map) projection is really longlat you need
EXTENT ? ? ? ?
and change the above "?" to valid min/max lat/lon in decimal degrees.
Or change the PROJECTION to your projection.
You should post the question to the mapserver email list.
