<p>Hi all,</p><p>Original question was posted here: <a href="http://gis.stackexchange.com/questions/19459/tilecache-and-mapserver-not-producing-images-and-raising-parsing-error">http://gis.stackexchange.com/questions/19459/tilecache-and-mapserver-not-producing-images-and-raising-parsing-error</a><br>
</p><p>Just a forewarning, I will try to be as extensive with my
question as possible. Due to a number of reasons why this might not be
working, I have posted all sorts of portions of my debugging below.</p>
<p>Web map located <a href="http://rinnerweb.arts.ryerson.ca/moot2_dev" rel="nofollow">here</a></p>
<p>Tile cache is being setup as a test run for the "hii_5" layer in OpenLayers. MapServer is the backend.</p>
<p>I am trying to get TileCache to cache images of my MapServer WMS.
However, no images are produced. The TileCache is "trying" to load the
tiles (as you can see on the live page), however, no images are
returned.</p>
<p>When I follow the <a href="http://rinnerweb.arts.ryerson.ca/cgi-bin/tilecache.cgi?LAYERS=HII_railroads&FORMAT=image/png&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG:3857&BBOX=-10592586.767623,5113378.756775,-9340242.496373,6365723.028025&WIDTH=256&HEIGHT=256" rel="nofollow">path</a> of one of the image tiles, I see this error:</p>
