Hi all, I'm receiving a http web exception "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've added a machineKey to my web.config under the <system.web>, which defines a validation key and algorithm. Only it's still coming up with the error still. Has anyone else had any experience with this error and can point me in the right direction? Cheers, Tiang
