I'm trying to get a subclass of the CuteEditor.Dialogs.FileBrowserPage to work in our UAT environment. I am getting a viewstate validate error message:

 [ViewStateException: Invalid viewstate.

(That's from my development machine, but the same error occurs on our UAT machine). It works fine in production. I believe that the problem is that you have to specify a "setting" parameter on the QueryString. We are doing that, but I believe we're setting an incorrect string here for UAT (for reference, it is "!3wEWAgUFZW4tYXUFAyRhMQtS!1kquEtliaQVybChbD6uJOyE3").

I understand this is related to the IP of the machine. Is there a tool that can tell me what the correct string should be? (I cannot find the version number of CuteEditor; apparently you're supposed to be able to find it by viewing source on a page with an editor, but all I get is 

  <!-- CuteEditor ceEditor Begin -->  with no version number).

Hi,

Try set property UseStandardDialog  to true, then open the same dialog what you are testing, you will get the full parameter from the url field.

  <CE:Editor ID="editor1" runat="server" UseStandardDialog="true">

        </CE:Editor>
