OK, I'm trying to use Hybridauth with laravel 4. However I seem to be getting the very common when trying to log in with facebook:
Authentication failed! Facebook returned an invalid user id.
I have read all the other posts, and have had no luck, so just hoping someone may be able to help me.
I followed this tutorial: http://www.mrcasual.com/on/coding/laravel4-package-management-with-composer/
And have tried several other configurations to no success.
Here is my config/hybridauth.php
<?php
return array(
    "base_url"   => "http://myapp.dev/social/auth/",
    "providers"  => array (
        "Facebook"   => array (
            "enabled"    => true,
            "keys"       => array ( "id" => "****", "secret" => "****" ),
        ),
    ),
);
And here is my route:
Route::get('social/{action?}', array("as" => "hybridauth", function($action = "")
{
    // check URL segment
    if ($action == "auth") {
        // process authentication
        try {
            Hybrid_Endpoint::process();
        }
        catch (Exception $e) {
            // redirect back to http://URL/social/
            return Redirect::route('hybridauth');
        }
        return;
    }
    try {
        // create a HybridAuth object
        $socialAuth = new Hybrid_Auth(app_path() . '/config/hybridauth.php');
        // authenticate with Facebook
        $provider = $socialAuth->authenticate("Facebook");
        // fetch user profile
        $userProfile = $provider->getUserProfile();
    }
    catch(Exception $e) {
        // exception codes can be found on HybBridAuth's web site
        return $e->getMessage();
    }
    // access user profile data
    echo "Connected with: <b>{$provider->id}</b><br />";
    echo "As: <b>{$userProfile->displayName}</b><br />";
    echo "<pre>" . print_r( $userProfile, true ) . "</pre><br />";
    // logout
    $provider->logout();
}));
So, when I access "myapp.dev/social" I'm brought to the facebook sign up page everthing seems to work fine, asks me to allow permissions to myadd.dev. After I click OK I am brought to the following URL: http://myapp.ie/social#_=_ where the error is displayed.
Not sure if this is relevant:
Just from observing other sites that in-cooperate a facebook login.. the redirect URL looks something like http://somesite.dev/subdomain/#_=_  . In other words they have a slash before the #=. Is this my problem, how do I fix it?? Very new to hybridauth so any help greatly appreciated thanks.
Oh I do realize that this post is very similar to other posts but I have yet to find a solution.
UPDATE: the exact error: Authentification failed. The user has canceled the authentication or the provider refused the connection.
