In my Portal web map I don't want any third party baselayers just my own Arcgis Server tiled layer. So far I have managed to set my own layer as basemap, but in this way I couldn't configure the popups. Is there as workaround for this? (I guess I would need an option to have just an operational layer.)
I have Portal for ArcGIS and ArcGIS Server, both are 10.3.1 version.
