Working with that copied mapfile and removing all those things helps me debug always - then later I can go back to the full mapfile, get that working at the commandline, then test with a manual request in the browser, and finally test in a client such as QGIS or OpenLayers.<span class="im HOEnZb"><br>

Hi,<br>
<br>
Regarding your issue, here is my advice for how I always debug such a<br>
situation:<br>
<br>
- I narrow down the mapfile until I am able to have the<br>
smallest/shortest mapfile that still generates the error (one layer,<br>
simple classification)<br>
<br>
- once I have that tiny mapfile, then examine that one problem layer<br>
(most times I also change the data in that layer, from something like a<br>
PostGIS connection to a local shapefile, and see if that changes anything)<br>
<br>
- for OGC/WMS requests, I will run the request directly from the MS4W<br>
commandline, such as:<br>
<br>
setenv.bat<br>
mapserv -nh<br>
QUERY_STRING="map=D:\ms4w\blah<wbr>.map&SERVICE=wms&REQUEST=GetCa<wbr>pabilities"<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
getcap.xml<br>
</blockquote>
<br>
And open that generated xml file to check for any errors or "WARNING"s<br>
in the response.<br>
<br>
Thank you for the positive feedback from you that MS4W is working great<br>
for you and your clients.<br>
