[mapserver-users] Can't get capabilities xml error message

[mathias cunault]

I did what you said : I copy and paste layer by layer from the old mapfile
to a new one, and test each time. I did not make any modification (as far
as i know). Now I can get the capabilities in FF ! Thanks.

Now I have the list of layers in QGIS. But I can't load them : it seems to
have a problem of connection with PostGIS. Log error says :
Error executing SQL: (connection pointer is NULL
) in msPostGISLayerGetExtent()[Wed Nov 23 16:33:27 2016].216000
msPostGISLayerGetExtent(): General error message. Error executing SQL.
Check server logs.
I guess that the logs in the message are PostGIS ones ?
