Validation of viewstate MAC failed

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.

Solution : Add this part to the web.config System.Web section:
<pages enableEventValidation="false" viewStateEncryptionMode ="Never" enableViewStateMac="false" />
