Diagnoses


The URLs associated with the Group Providers were no longer valid.

Resolution

To remove the invalid SP group providers, you would need to manually delete them from the database. Kindly follow these steps:-
1. Stop the K2 Service.
2. Make a backup of the K2 DB.
3. Delete the invalid group provider record from the HostServer.GroupProvider table.
4. Start the K2 Service.
