[Qgis-user] failed to add WMS layer

[Andrea Peri]

Have you the cache to zero size?
I discovered this kind of strangenissue some weeks ago

If the qgis cache size is turn to zero the capabilities fail when go to add
the map to the Canvas.
This issue is on only with some wms (mapserver, geoserver) do not with
qgisserver.

I dont know with arcgis rest services.
