Konqueror is kind of limited. But it works in all other browsers (Google
Chrome, Firefox, Opera, Safari, Internet Explorer (>= 8))

good

Strange - this should work before you continue with QGIS Web Client.

Your best friend is Firebug in Firefox or the Dev-Tools in Google
Chrome. Look for a GetProjectSettings or GetCapabilities request.

Copy that request and run it manually. See if it works.

That is most likely wrong - it should be something like:

/cgi/qgis_mapserv.fcgi or /cgi-bin/qgis_mapserv.fcgi or
/qgis/qgis_mapserv.fcgi (only if you defined /qgis as a CGI directory)

no - don't do that. This is handled by the client.

To me it looks like the GetCapabilities or GetProjectSettings request is
not issued correctly - this is why it is stuck in the loading phase.

It would help if you could send us the URL to your server so we can have
a look at it in Firebug or Google Chrome dev-tools.
