After successfully performing an upgrade to 4.3.5 I now receive the following message whenever I try to to login as anyone. 

A critical error has occurred.
Method not found: 'System.String DotNetNuke.Entities.Users.UserController.GetRegistrationStatus(Microsoft.ScalableHosting.Security.MembershipCreateStatus)'.

My web.config is as follows:  Any help would be appreciated.
