  <blockquote>
    <p>The anti-forgery token could not be decrypted. If this application is hosted by a Web Farm or cluster, ensure that all machines are running the same version of ASP.NET Web Pages and that the  configuration specifies explicit encryption and validation keys. AutoGenerate cannot be used in a cluster.</p>
