title: TileCache with Mapnik for OpenStreetMap
body: <p>I have an OpenStreetMap server that uses TileCache to serve tiles. The tiles are generated with Mapnik. I have configured the Mapnik XML stylesheet and I can generate an image with the OSM Mapnik tool 'generate_image.py'. That image is correct and looks good.</p>
  
  <p>My TileCache server will serve tiles from my OSM layer; however, all I get are tiles with the background/water blue. I get no land forms, I get no street data. Can anybody help with this?</p>
  
  <p>TileCache Config:</p>
  
  <pre><code>[osm]
  type=Mapnik
  mapfile=/var/maps/bin/mapnik/osm.xml
  spherical_mercator=true
  </code></pre>
  
  <p>I am using OpenLayers to show the map. I am using a TMS layer to call the TileCache server. Like I said, I get tiles returned, they are just nothing but blue.</p>
