When i try to add a link to the top nav bar, I am doing this from the cms so not from code. I get the security validation invalid error. http://img233.imageshack.us/img233/5761/errorcs.png

On the internet, i can find lots of reasons why this error can occur when using your own code. The thing is that i am not using any custom code.

The only thing i use is a custom master page. When i set the site to use the standard master page i do not get the error. So obviously the error is in the master page. So my question is:

Has anyone had this problem before?

Does anyone know the solution to my problem?

Any help is appreciated.

Note : This question is still not answered

Can you check to see if you've included this in your masterpage?

<asp:ContentPlaceHolder id="PlaceHolderFormDigest" runat="server">
    <SharePoint:FormDigest runat="server"/>
</asp:ContentPlaceHolder>

Also, Randy Drisgill has some start master pages available on Codeplex that you can use. It has all the required content place holders on it to ensure your site functions normally.

  • Thanks, i do have this contentplaceholder. I used the basic master page that Randy Drisgill provided. To be certain i will recheck all placeholders. Thanks for the input – nldev Jul 28 '11 at 14:50
  • i looked over every starter page and checked every content place holder and i have them all, any other suggestions? – nldev Jul 29 '11 at 7:42
  • do you see anything in the ULS logs with that correlation ID? – Eric Alexander Jul 29 '11 at 12:05
  • yes, i added it to the main question – nldev Aug 1 '11 at 9:33
  • Joel just blogged about some security validation stuff, perhaps that's what your running into, sharepointjoel.com/Lists/Posts/Post.aspx?ID=470 – Eric Alexander Aug 1 '11 at 15:05
