Has anybody seen and fixed the following error mesasage:

A critical error has occurred.
Validation of view_state 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.

 

This comes up randomly and I have no idea why, it came up when using DNN v.4 and I was hoping that the upgade to v.5 would get rid of it but it didn't.

 

Any help would be much appreciated.

 

Thanks

 

Sarah
