i am getting the below error message in my website:
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....
I had inserted the below code in web config file
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never" />
but still getting the same error.
Please provide the way to get rid out of it.
