Laravel 4.2 application occurs unnecessary redirection after uploading live server

My laravel(4.2) application is working fine on localhost(xampp). But after uploading into live server when trying to login, it is showing a blank page with a message saying "redirecting to my home url". It also throws a login error

Sorry for my weak English. Please help me. I am attaching my htaccess below:

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

RewriteEngine On

# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ /$1 [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

Here is my Controller function.

public function adminLoginCheck() {
$validation_rule = array(
    'username' => array('required', 'min:5', 'max:50'),
    'password' => array('required', 'min:6', 'max:50')
);
$validation = Validator::make(Input::all(), $validation_rule);
// Validation Check
if ($validation->fails()) {
    return Redirect::to('/')->withErrors($validation);
} // After Validation Authentication start
else {
    $athentication = Auth::attempt(array('username' => Input :: get('username'), 'password' => Input :: get('password')));
    // When Authentication True
    if ($athentication) { 
        $rememberme = Input::get('remember');
        if(!empty($rememberme)){
            //Remember Login data
           Auth::loginUsingId(Auth::user()->id,true);
        }
        //Redrict to the Target page
        return Redirect::intended('adminDashboard');
    } else {
        //Redrict Login Form with Authentication error massege.
        return Redirect::to('/')->with('authentication_error', 'Username or Password is not valid!');
    }
}

}

My Auth filter is given below:

Route::filter('auth', function(){if (Auth::guest()){
if (Request::ajax())
{
    return Response::make('Unauthorized', 401);
}
else
{
    return Redirect::guest('login');
}  }  })

All of the blade templates are available.I am not understanding why the blank page is appearing with the redirecting message.Even when submitting login without inputting

username and password Here is the live url http://noveltyshop.tech-novelty.com/ user:admin pass:pass

My route:

Route::get('/', array('as' => 'admin', 'uses' => '[email protected]'));
Route::post('/login', array('as' => 'login', 'uses' => '[email protected]'));
Route::get('/adminDashboard', array('as' => 'adminDashboard', 'uses' => '[email protected]')); 
Route::get('/logout', array('as' => 'logout', 'uses' => '[email protected]')); 
Route::get('/updateUserProfileForm', array('as' => 'updateUserProfileForm', 'uses' => '[email protected]'));
Route::post('/updateUserProfile', array('as' => 'updateUserProfile', 'uses' => '[email protected]')); 

[email protected]

public function adminDashboard() {
    return View::make('admin.pages.admin_dashboard')->with('title', 'AdminDashboard');
}

As you are using Laravel 4.2

You shall handle this in your Controller.

Here's the default way that we deal with

if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return Redirect::intended('yourTargetPageAfterLogin');
}

In the auth filter you shall have this

Route::filter('auth', function() {
    if (Auth::guest()) {
        return Redirect::guest('login');
    }
});

Note : Make sure you have the blades as you defined in your Controller

Suggestion : Why not upgrade to 5.1 ?
