Constantly I got this: I tried also removed templ folder, I add in web.config machinekey and always is the same 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.
