Facebook Connect works offline, but not online "This webpage has a redirect loop" - facebook

Question

Access to my developed website is done using facebook connect.
Everything is OK offline, but not online. I get a navigation error (using Chrome) "This webpage has a redirect loop" :
The webpage at https://www.facebook.com/dialog/oauth?client_id=209633612480053&redirect_uri=http%3A%2F%2Fwww.bluward.com%2Faccess%2Flogin_facebook&state=299262ddf89afbf382452df89c9a2ce8&scope=email%2C+user_birthday%2C+user_about_me%2C+user_location%2C+publish_stream&fbconnect=1#= has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.
Here is the PHP code (using CodeIgniter framework):
public function login()
{
// Get the FB UID of the currently logged in user
$uid = $fb->getUser();
// If the user has already allowed the application, you'll be able to get his/her FB UID
if($uid) {
try {
$profile = $fb->api(array(
'method' => 'users.getinfo',
'uids' => $uid,
'fields' => 'uid, first_name, last_name, pic_square, pic_big, sex, birthday_date, current_location, email'
));
// Only the first user.
$profile = $profile[0];
} catch (FacebookApiException $e) {
return false;
}
// Do stuff when already logged in.
return $profile;
} else {
// If not, let's redirect to the ALLOW page so we can get access
redirect($this->getLoginUrl(array(
'scope' => 'email, user_birthday, user_about_me, user_location, publish_stream',
'fbconnect' => 1
)));
}
}
And depending on the profile info, I check if the user already exists on database, then log him/her, and if not exists on database, signup him/her.
Update:
When I clear Facebook cookies, the redirect to login page is successful, and I'm able to fill email/password.
Unfortunately, when I click "log in" button, I get the same error message as I displayed above.

It looks like your using and older version? Here is how i would handle issue with php-sdk 3.1.1 "the most current version".
require 'src/facebook.php';
$facebook = new Facebook(array(
'appId' => '135669679827333',
'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx'
));
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$params = array(
scope => 'read_stream,publish_stream,publish_actions,read_friendlists',
//redirect_uri => $url
);
$loginUrl = $facebook->getLoginUrl($params);
echo '<script> top.location.href=\''.$loginUrl.'\'</script>';
};
