I am a NOOB to OSM and am attempting to build a simple local tile server on a Raspberry PI.
If this has been asked before please forgive me and point me to where the question is.
I have followed the instructions found at this site: http://wiki.openstreetmap.org/wiki/OpenLayers_Local_Tiles_Example to build a simple local server.
I have downloaded the tiles using jTileDownloader.
When I call up the web page I get a quick flash of the tiles and then blank screen with just the tile grid displaying. If I zoom in and out, I also get a quick flash of a map and then just the grids.
Can someone help me, with what I am doing wrong?
