I am trying to edit maps that I have previously created in my Map Viewer. The server was rebuilt recently and federated with the Portal (again). I have previously existing maps and layers that I am attempting to use. It is working for the most part, but occasionally I can't save my map after having added an additional layer. It seems that it occurs when I add a Map Image Layer to the map. I can "Save As", but then with the addition of another such layer, I cannot and have to rename once again.
I am an admin to the Portal and own all the data sources that reside on our Server and in our Data Store.
Any ideas as to what is stopping me from saving the map?
