[Qgis-user] WMS in QGIS: no map displayed

[Marco Hugentobler]

Hi Yves,

What is the capabilities output for the layer departements? I have no problem 
with the wms layers I'm using here, so it may have something to do about how 
the server specifies the bounding box in your particular case and how QGIS 
interprets it.

Regards,
Marco
