Authentication error: Opauth returns error auth response.

[Abdul Mannan]

Hi,

Everything is working fine except when user returns back from authenticating with Facebook, it takes alot of time and after this it returns this error.

Authentication error: Opauth returns error auth response.

Array
(
    [error] => Array
        (
            [provider] => Facebook
            [code] => access_token_error
            [message] => Failed when attempting to obtain access token
            [raw] => 
        )

    [timestamp] => 2015-03-31T18:06:42+05:00
)

I'm on localhost and application is configured correctly on fb. Also i have checked php.ini and extension=php_openssl.so is enabled and allow_url_fopen is also On. Also added a backslash with the callback url, but still it is not working.

This is my callback url (  http://localhost/testing/facebook_2/Opauth-bundled-example/callback.php/ )  and after redirection from facebook, callback becomes this ( http://localhost/testing/facebook_2/Opauth-bundled-example/callback.php/#_=_ ).

I have searched and applied every possible solution I found but no success. Please help.



Thanks
