Hello!

Thank you for your answer!

In QGIS Desktop, everything seems ok, the GetCapabilities-Request looks 
also ok - here the head of the answer cut 'n copied:

<WMS_Capabilities version="1.3.0" 
xsi:schemaLocation="http://www.opengis.net/wms 
http://schemas.opengis.net/wms/1.3.0/capabilities_1_3_0.xsd"><Service><Name>WMS</Name><Title>QGIS-Server</Title><Abstract/><OnlineResource

Concerning the BBOX:
I tried it with the following URL (for a small area close to the town of 
Salzburg), but again, no success, just a white canvas:

http://myserver/cgi-bin/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/png&CRS=EPSG:4326&WIDTH=500&HEIGHT=500&LAYERS=mypostgislayer&BBOX=12.96,47.79,12.98,47.81

Thanks,
Albin
