I have upgraded ArcGIS Enterprise from 10.6 to 10.7.1 recently and noticed that the Portal items are somehow corrupted upon completion of the upgrade. The items have no title or thumbnail. The item properties page just spins and never actually comes up, and opening the item properties from the Sharing Rest site gives a 500 error. Most of these items are map services that reside on the federated Hosting server. Reindexing the content did not help. From within ArcGIS Server, I can see that the map services are behaving just fine. The issue is with the Portal items themselves. Has anyone else experienced this issue or anything similar?
