Validation of viewstate MAC failed.

Jan 27, 2008 at 5:42 PM
I get the "Validation of viewstate MAC failed." problem when I click the "Log In" button on the startpage.
It works on other pages, but on the startpage I cannot login or logout.

Has anyone had this problem and found a solution?
No, it does not work to set the enableViewStateMac to false in the webconfig. In that case I don't get the error, but I don't come to the login-page at all....

It's driving me nuts!!
