Viewstate verification failed. Reason: The viewstate supplied failed integrity check. RRS feed

  • User-932012589 posted

    I have a .NET 4.5 website that is intermittently getting viewstate verification errors on multiple pages. In a one week period the error occurred 36 times. Most of the posts on this forum for the error seem to be related to the site running on a web farm. In my case there's only one server.

    From the web.config:

     validationKey="46F1..." (128 characters)
    decryptionKey="4702..." (64 characters)
    validation="SHA1" />

    The application pool is scheduled to recycle at 1am when no one is using the site. What else could be causing this?

    Thanks for your help,
