Validation of viewstate MAC failed error
Hi:
I've been encountering the following error :
Server Error in '/' Application.
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 algorithmn. Autogenerate cannot be used in a cluster.
This error occurs infrequently. I'm using a web hosting account.
I modified my web config file with the following code but to no avail:
system.web>
<customErrors mode="Off"/>
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never" />
</system.web>
Why does this occur and how do I correct it?
