Validation of viewstate MAC failed

[NidhiKanu]

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. N!dh! :)

Kind Regards Pratik Shah
