Hi Andreas,

yes, with the map parameter I could go a step further, the alaska layer appeared. But while trying to import it, the following internal server error was shown:

Kartenabfrage-Fehler [Fehler:Error downloading http://localhost/qgis-mapserv/qgis_mapserv.fcgi?map=/Library/WebServer/Documents/alaska.qgs&&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=-15256791.5967269185930490,482471.5356363095343113,15452694.4898276831954718,30602207.0081926248967648&CRS=EPSG:2964&WIDTH=1084&HEIGHT=1063&LAYERS=alaska&STYLES=&FORMAT=image/jpeg&DPI=72&MAP_RESOLUTION=72&FORMAT_OPTIONS=dpi:72 - server replied: Internal Server Error; URL: http://localhost/qgis-mapserv/qgis_mapserv.fcgi?map=/Library/WebServer/Documents/alaska.qgs&&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=-15256791.5967269185930490,482471.5356363095343113,15452694.4898276831954718,30602207.0081926248967648&CRS=EPSG:2964&WIDTH=1084&HEIGHT=1063&LAYERS=alaska&STYLES=&FORMAT=image/jpeg&DPI=72&MAP_RESOLUTION=72&FORMAT_OPTIONS=dpi:72]

The layer was somehow imported, i.e. i can open the preferences, but no data are shown.

Any idea?

Thank you
Marcel

It means the behaviour of the WMS-Connection is the same with or without the project file alaska.qgs. So, it's probably not a CRS issue. It seems that the QGIS Server doesn't see the alaska project file at all.

But somehow I don't understand how it works… I afraid my QGIS Server configuration is not correct. But at this point I'm lost.
