Hi,
So we are on arcgis enterprise v11.3. we have been unable to create a "Site Hub" in Portal. We had an existing site but we are unable to save and publish.
Has anyone had a similar experience and/or can offer ideas on what we might check to resolve this. Experience builder Storymaps and other apps work fine.
thank you
Could you please share the error screen shot?
Also , check if relation database is validating from your hosting server.
