Mitchel,

User account module which was working fine earlier throws this error messgae now. I do not understand why DNN is behaving in this manner. The same module works fine for other portals but fails to run for some portals. And the best part is you can see the list of users in this module when you add one user. But if you want to directlly search a user, it is not possible now.

I have tried searching for such records. What I found is there are many null values in one field 'Email'. So I have update all these null values but still getting this error message for specific portal.

Does users of different portals are updated in different tables or ALL USERS of ALL PORTALS are updated in same table dbo.User 

leupold,

Could you please refer me any upgrade document for these versions ? Let me know the URL from where I can download these documents (If any)
