<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">I am experimenting with a very simple/basic WMS served by UMN Mapserver.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">For some reasons, GetFeatureInfo does not work, although it is "advertised" as available in the GetCapabilities reponse.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">Here is the test service:
<a href="http://159.100.248.156/cgi-bin/mapserv.fcgi?map=/home/ubuntu/umn_mapfiles/cave_entrances.map">

<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">and a link to the GetCapabilities request<o:p></o:p></span></p>

<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">When I load this layer, i get the two points in the data set, but I can't query them. QGIS says "No feature found at this position" and in the network debugging session I see that no request
is sent to the server.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">Do you have any idea what might be wrong with this WMS service?<o:p></o:p></span></p>
