  3. Create a profile
     
    Result: Intermittent error:
    Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
     
    Fix: Add a <machineKey> to web.config
