I have started to receive this error on my site when i upgraded this to DNN - 7.4.2. It appears that it cannot find the portalid  present in the url in order to pull out the decryption key. Any ideas on how to solve this issue?

URL: /LinkClick.aspx?fileticket=v9wAg9u2_YA%3d&tabid=162&portalid=0&mid=506

Solved.

The crypto section was missing from my web.config file. Added this to the web.config. found on a fourm @ http://www.dnnsoftware.com/forums/threadid/499007/scope/posts/dotnetnukeservicescryptographycryptographyprovider-issue-after-upgrading-to-722

something odd going on here - the issue indicates a problem with the CryptographyProvider which was only introduced in 7.2.1 (and your issue says 7.1.2). That part I don't understand.

As to why it might be happening, it's probable that you are missing the references in web.config -check it and look for the following (usually just before the </dotnetnuke> tag)

  <cryptography defaultProvider="CoreCryptographyProvider">

      <providers>

        <clear />

        <add name="CoreCryptographyProvider" type="DotNetNuke.Services.Cryptography.CoreCryptographyProvider, DotNetNuke" providerPath="~\Providers\CryptographyProviders\CoreCryptographyProvider\" />

      </providers>

    </cryptography>
