[Qgis-user] QGIS Web Client - QWC Issues loading map (server loads fine)

[Bernhard Ströbl]

Hi Carlos,

I recently had the situation that one of my layers contained polygons 
with errors (PostGIS). It was drawn in QGIS desktop but did not show up 
in QWC. I did not investigate further but fixed the errors.
Furthermore I used to have a layer which eventually contained no 
features, thus QGIS server could not detect the bbox and sent some weird 
bbox (cannot remember if this was fixed (should send the bbox of the 
project IMHO), have not tried it again but keep at least one feature in 
the layer in question).

The difference between WMS 1.3 and WMS 1.1 in bbox is that 1.3 uses the 
axis order of the CRS whereas 1.1 always used 1st axis = x 2nd axis = y 
(see this [1] for details) QWC uses WMS1.3 though so you might run into 
other issues if you use WMS1.1.
