Last week I upgraded a customer's site with3.7 SP4 for .net 3.5
This customer has a secure client area and we discovered a few days ago the registration was failing every time with "DuplicateEmail" being returned.
We then tested registering through Sitefinity Admin rather than via our public form and we got the same error.
After much mucking about it dawned on us that maybe it was the service pack and so we rolled back the service pack affected files.
We tested the form and have confirmed with only a rollback to SP3 it is now working fine. The offending bit of code is below:
Telerik.Security.UserManager manager =
manager.CreateUser(Username.Text, Password.Text, Email.Text.ToLower(),
The CreateUser method always returns the status MembershipCreateStatus.DuplicateEmail without fail whether a user's email exists or not.
Can you please look into this asap a it could be a disaster for many users.
