Error when changing language users setting
I'm in Ihub Administration and I want to change the language setting of a user. The setting is grayed out, but I can still change it. When I do so and I click save I'm asked to confirm the change. When I click OK I get an error:
3063: The specified operation is not valid under external registration.
Any idea why I get this error and how I do can change the language setting?
Thanks in advance!
