exporting file structure

[Mark Lochrie]

Hey all,

only just started using gheat a couple of weeks ago, really like it
got it working and produced my map, now i want to take those files and
move onto a different server so i can keep the results that were
recorded, i integrated the update for the auto gen tiles for 5 zoom
levels, and ran the server to generate the tiles, now i moved the file
structure onto a different server, the map shows all heat areas, but
doesn't show the empty areas where there are no heat overlays.

Does or has anyone experienced this problem before and could give me a
pointer, i do have the url where my map is located which is

Many Thanks
