At which exact step do you get this error..?

after I log into facebook i do not get redirected to the result page see the developer tools message below:

Failed to load resource: the server responded with a status of 400 (Bad Request) https://graph.facebook.com/oauth/acce...
thanks

https://graph.facebook.com/oauth/acce...

If you look at the end of the URL, there is this:
code=undefined%3D_

That's probably why it fails...

I see that but how do I fix it? I think I have followed the tutorial and it was working before. I have redone the tutorial several times just to make sure. after I click on the login to facebook button it seems I'm being redirected to the results page but I do not see the get data button. just a blank page with the following url:

http://tiggzi.com/view/aef6ab9e-9086-...

when I enter this url in facebook debug tool I get :

{
"url": "http://tiggzi.com/view/aef6ab9e-9086-...,
"type": "website",
"title": "resulted",
"updated_time": "2012-05-30T03:26:49+0000",
"id": "10151169583054741"
}

We'll test the tutorial again.. we did push some changes into production with regards to how callback parameters are handled.

I updated the tutorial on how to fix it (see #3 box)

Thanks that worked, but now I get the following error

XMLHttpRequest cannot load url: https://graph.facebook.com/oauth/acce.... Cross origin requests are only supported for HTTP.
TypeError Cannot call method 'split' of undefined

Try http:// instead of https://
