Hello please help..

i enabled SSO settings in my YAF and added in the app.config:




When i choose:
"Login with an user Account that is connected with Facebook. Or if no account is found a new account will be automatically created in the forums."

and click "login with facebook" it shows nothing. This is the URL after i clicked:
http://www.cebuprogrammers.net/auth.aspx?auth=facebook&code=AQCl-FU77dBYGRZIeKiUof3yaPe_R4heGyBivp0ddIIpEHuiDT2ukmC8hliYNqwe5OCN-tVy1YIVtvyZ2balEH6ds9-Z1JQdkOYh9eQMwBAIFZUXj4GO5JIXlwiRh5a8tGypSgFN40WmAbv8ij5htkewHplhTcqHPfYGJrWi-z3G1URvPT-jnGWaUL5-llzu_xEsPn4HAs3fTZn_Qr4c7yI8JtUn0F3y-1C_J7w-_8JO1_S8G4Bz5h-HWvsRrC36B-zAM3LDmL15vi4omsYU1NTV1FVv4DOamsvT2ssKL3xugDSBgPJ0TI4CtE8D-2aDhAurQLBSE2vOAp9AYQK7mHT-#_=_ 

And when i reload this is the error:

Did you set up the Facebook App correctly?

thanks for you reply tha_watcha.

I tried it today, and when i click "login with facebook" it can now display the facebook login form BUT
the problem after i click "login" in facebook login form, it will show nothing.. and the user isnt registered.
The error message is the same as above.

Hello sir tha_watcha

i setup correctly based on that link.

This is what happens:
Currently i am not logged in my facebook account.
1.) Click "Login with facebook" to register.
2.) The webpage will redirect to facebook url (www.facebook...) and display facebook login.
3.) I input my facebook account login and click "Login"
4.) The webpage will redirect to my YAF forum with this link:

5.) It will display nothing in my YAF forum. I dont know why it will not redirect to my forum home.
6.) If i reload the webpage i will get the error msg:

[WebException: The remote server returned an error: (400) Bad Request.]

I really need your help sir.. i am stuck in this problem. Btw i am using the YAF Version 2.1.2.

YES! finally i figured out what is the problem!

the problem is that if the facebook user's email address is not yet confirmed by facebook it will fail to do Single sign on.
