Scringo Help (Freezes / Sigbart)

Question

I have Scringo all set up in my application. However after the user logs into facebook and returns to the app the app freezes and my log shows this error.

Any help would be great!!

I think that the problem is because your FB app includes some advanced setting that tells Facebook to use a response format that should be activated by default only in Oct, 2012 and your Scringo version still doesn't support it.

To make it work you should either: 1) Update to the latest Scringo version or 2) Go to your FB app settings (where you registered your FB app), and choose the Advanced Settings. There, you'll see a Migration section. Make sure the following field is DISABLED: October 2012 Breaking Changes (this will work until 3, Oct 2012)
