Hi,
thanks for the answer, but now I get pink broken tiles :( ... why? The example is working without Tilecache. Second, a short question concerning my second problem (see my last email) - does Tilecache have probelems with the Openlayers "scales" attribute, because without this attribute Tilecache is working but when I add it I just get nothing.
best regards,
Martin
