[ka-Map-users] precache2.php

[ramesh karra]

After re-installing kaMap using fgs installer,
precache2.php is working fine but the background color
of the map is displayed as black eventhough the
IMAGECOLOR is set to '235 235 235' in the map file.
Same map file would displays correctly if I do not use
precache2.php and use the web interface to create the
tiles correctly.

Any ideas on why this is happening?

Thanks a lot
Ramesh
