Note: When you are adding a tile cache to be used as base mapping, ensure the extents for the CRS in the Projections table (found in webMapLayersConfig.db) match the ones defined in the tile cache.

For example you create a Tile Cache in British National Grid with the extents 0,0,700000,1500000. Locate the SRID for this projection (27700) in the projections table and ensure the extents match.
