[Qgis-user] Project not loading in web client

[Voytek Lapinski]

Hi All,

I am experiencing a problem on a new ubuntu/apache installation of the 
web client, where a project file is causing the web client to fail after 
loading the layers, but before drawing a map.

The problem is similar to 
http://osgeo-org.1560.x6.nabble.com/Problem-loading-map-using-QGIS-web-client-on-Windows-7-td5029267.html 
, which I've worked through to no avail.

The GetProjectSettings call to the server from the web client seems to 
work fine, and generates a valid looking result when I call it directly. 
The web client shows the layers returned in the layer list sidebar, but 
never generates a GetMap call. Am I right in thinking that this should 
be the next step?

The last HTTP request from the webclient is to the googleapis 
Authentication Service which seems strange as that map doesn't use 
anything from Google. After that it just stays on the message 'Loading Map'.

There are no error messages in the apache log, apart from the following

Warning 1: Unable to find driver ECW to unload from GDAL_SKIP 
environment variable.
Warning 1: Unable to find driver ECW to unload from GDAL_SKIP 
environment variable.
Warning 1: Unable to find driver JP2ECW to unload from GDAL_SKIP 
environment variable.
Warning 1: Unable to find driver ECW to unload from GDAL_SKIP 
environment variable.
Warning 1: Unable to find driver JP2ECW to unload from GDAL_SKIP 
environment variable.

Am I right in believing that that these shouldn't cause failure, however?

I am able to load the demonstration examples (HelloWorld and 
NaturalEarth) in the web client with no issues, so am assuming it's 
something to do with my particular project. The project itself loads 
fine in QGIS on the desktop machine I created it on. The desktop and 
server are both ubuntu 12.04, and are identical, from the point of view 
of GIS system software. Qgis desktop and server is 2.0. Postgis is 2.1. 
The web client is the most recent version from the git repository. All 
the project layers are stored in local postgis databases (version 2.1 on 
postgres 9.3) replicated on both machines exactly.

It seems like it should be something straightforward to do with the 
project, but in the absence of any useful error or log messages, I don't 
really know where to start.

Any help would be much appreciated.
