[ka-Map-users] precache2.php

[Stephen Woodbridge]

Ramesh,

Not sure I can add much more to this. All my mapfiles have all the 
layers set to STATUS default and I have no GROUPs defined. This causes 
ka-map to generate transparent tiles. I my case I have to hack tile.php 
and precache2.php and comment out all the lines that set the image to 
TRANSPARENT. It is a real pain because half the time I forget to do this 
and since it has been 6 months since I last did it, I always forget to 
change something.
