[mapserver-users] RE: [MapServer-users] Blank Image when zoom ing

[Nuno Alves]

I've allready change the MINSCALE and MAXSCALE properties for each data
layer and for WEB properties too. I´ve changed
too the extensions of the map again, but nothing. I have had another idea,
that was to "clean the trash" from my map
files, that i allready did, but the problems persists.
I've attached my MAP file to this mail. Any help would be appreciated.

	Thanks, 
		Nuno Alves

Not knowing much about your application, it sounds to me like your layers
are scale dependent.  In other words, they are set to only show between a
maximum and a minimum scale value.  

Check the MINSCALE and MAXSCALE properties for each of your data layers.
Are the layers set to show at the scales you want to see them at?

If this doesn't work, post the text of your Map file.  Perhaps some of the
other folks on the list could diagnose it from the mapfile.
