[Qgis-user] where to install qgis-web-client on Mac OSX 10.8.4

Hi Marcel,

If the GetCapabilities command is answering it means that at least parts
of the QGIS server is running ok.

The WMS server supports the following commands:

GetCapabilities
GetMap
GetLegendGraphic
GetFeatureInfo
GetPrint

The GetCapabilities is always at the start of a session or connection to
get the service metadata.

In your case it looks like a CRS issue. You should make sure that in
your new empty test project you specify the same projection as in the
Alaska sample project. There are reprojection options - but for a start
it is easier if server and client are in the same projection. It will
also be faster if no reprojection has to be done.

Once QGIS works fine as a client, you can go on and configure QGIS web
client. Before, it makes no sense and you should first fix the server.
