I did a forum search and I'm not seeing this. Figured I ask, here's the error I get after database and user config steps. I can't seem to move past it.
The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.sf_StagedPageContent' and the index name 'PK_sf_StagedPageContent'. The duplicate key value is (127, 7e3c6cc8-4490-44e1-b750-9628733ae322, 8).
Could not create constraint. See previous errors.
The statement has been terminated.
I did an update to our Release Sitefinity 3.7 SP2
3.7.2057.2 - standard
