Everytime when I take slightly to long to make a post on my YAF forum, I keep getting a 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.

Is there anyway I can get this issue sorted. Tim-outs also seem to happen when you have not clicked anything for a while on the forum, and then click a topic etc.
