I am using
QGIS 2.14 on Windows 10, and
GeoServer 2.8.3 on Windows 2008 Server (VPS).
QGIS manages my GeoServer layers with Web Feature Service. I would like to change the geometry or attributes of the layers stored in GeoServer with QGIS, but I can't. The added points appear on the web map, but I can't delete or modify these points and don't know why. No errors reported, seems like the changes have been saved. Furthermore I can't draw new lines and polygons: in the attribute panel the data appears, but it has no geometry so I can't visualize it.
Where's the problem?
