After upgrading existing dnn site from 441 to 451. all works on site. except, i cannot login as host or admin
i am receiving

A critical error has occurred.
Object reference not set to an instance of an object.

upon investigation i see the error happening in the code behind of Signin.ascx
Private Sub cmdLogin_Click(ByVal sender As Object, ByVal e As EventArgs) Handles cmdLogin.Click

            If (UseCaptcha And ctlCaptcha.IsValid) OrElse (Not UseCaptcha) Then
                'Try to validate user
                Dim loginStatus As UserLoginStatus
                Dim objUser As UserInfo = UserController.ValidateUser(PortalId, txtUsername.Text, txtPassword.Text, txtVerification.Text, PortalSettings.PortalName, ipAddress, loginStatus)

the preceding underlined is where the error occures,

with the following exception.


System.NullReferenceException was unhandled by user code
  Message="Object reference not set to an instance of an object."
  Source="DotNetNuke.Provider.AspNetProvider"
  StackTrace:

make sure, that the database connection strings in your web.config file do not have a trailing ";"
