Session key invalid or no longer valid

Mar 6, 2008 at 5:51 PM

When removing my app and then trying to navigate to

I get the error message 'Session key invalid or no longer valid'

I know I have to add a post-remove URL to a remove page, however I am using Version 1.6 of the Toolkit.

What should the code behind on this page be? I think I need to set the SessionKey and UserID to null?

Your post remove URL "Cannot be a Facebook-framed page." it needs to point to your page on your server instead. (says so in little text under the post-remove url in your app settings)

"URL at which you want to be notified when a user removes your application from their Facebook account.
Cannot be a Facebook-framed page."

perhaps that helps?
