I want to add a WMS layer in my map. I select the server and obtain the list of layers that are published there. I select one of them (the problem is the same with all layers), but QGIS does not load it, instead returning a message saying invalid layer - Impossible to calculate extension.
I think it could be a problem of projection, because it is not declared by the server, and I know it is lat/lon WGS84 (not projected).
Any help ?
