I'm getting a "viewstate mac" failed exception and none of the info I've read on it here or elsewhere seems to apply.  No web farm... DNN 7.04.  It happens when you are logged in and the session expires.  It occurs when you then try to take some action like press a button that causes a postback.  This is a fresh install.  Any ideas on how to eliminate the exception?  It should go to the login popup, not give an exception.

Hi Richard,

You can try a quick fix by modify the web.config:
Add the following to the web.config:

<pages enableEventValidation="false" viewStateEncryptionMode="Never">
or
<pages enableViewStateMac="false">
