[OpenLayers-Users] TileCache and Openlayers

[Michael Shishcu]

Hi.

Your tilecache layer is defined as WMS, so i think you can remove
mapfile=...
Now the main:
try adding levels=..., maxresolution=..., resolutions=... in your
tilecache.cfg
these settings must be the same as for openlayers map

regards, michael
