[MS4W-Users] Mapserver displays an empty map using layer from postgis

[Ronald Muchini]

I have a raster layer in postgis, which I'm trying to display it in the browser using the following code. My Postgis is Installed in the directory, "C:\Program Files(x86)\PostgreSQL\9.3\bin" and mapsever directory is "C:\ms4w". 


MAP

END #map



Im calling the webpage using the url below:
"http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/apps/Lakes/config.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&LAYERS=ras&STYLES=&CRS=EPSG:4326&BBOX=5,97,21,106&WIDTH=600&HEIGHT=800&FORMAT=image/png"


No errors pop up but the browser displays an empty map space.
How can I resolve this issue

Thanks in advance
