My site loads different pages on different Operating Systems

I'm going through a very strange problem.

When using Windows (Windows 7), my page loads as expected:

@extends + index.php

In Linux (Ubuntu 13.10) he is redirecting me to the / user / login route for no reason:

@extends + login.php

On both systems, the folder was copied from the dropbox without the vendor and later installed via composer install

I thought the filter or the routes might have something conflicting, but it does not make sense for one system to load normally and the other to call for an unexpected page.

Route:

<?php

/** ------------------------------------------
 *  Route model binding
 *  ------------------------------------------
 */
Route::model('user', 'User');
Route::model('comment', 'Comment');
Route::model('post', 'Post');
Route::model('role', 'Role');

Route::resource('upload', 'UploadController');


/** ------------------------------------------
 *  Admin Routes
 *  ------------------------------------------
 */
Route::group(['prefix' => 'admin', 'before' => 'auth'], function()
{
    Route::pattern('user', '[0-9]+');
    Route::pattern('role', '[0-9]+');

    # User Management
    Route::get('users/{user}/show', 'AdminUsersController@getShow');
    Route::get('users/{user}/edit', 'AdminUsersController@getEdit');
    Route::post('users/{user}/edit', 'AdminUsersController@postEdit');
    Route::get('users/{user}/delete', 'AdminUsersController@getDelete');
    Route::post('users/{user}/delete', 'AdminUsersController@postDelete');
    Route::controller('users', 'AdminUsersController');

    # User Role Management
    Route::get('roles/{role}/show', 'AdminRolesController@getShow');
    Route::get('roles/{role}/edit', 'AdminRolesController@getEdit');
    Route::post('roles/{role}/edit', 'AdminRolesController@postEdit');
    Route::get('roles/{role}/delete', 'AdminRolesController@getDelete');
    Route::post('roles/{role}/delete', 'AdminRolesController@postDelete');
    Route::controller('roles', 'AdminRolesController');

    # Optional
    Route::get('faq', 'AdminUsersController@getFaq');
    Route::get('profile', 'AdminUsersController@getProfile');
    Route::get('mural', 'AdminUsersController@getMural');

    # Admin Dashboard
    Route::controller('/', 'AdminDashboardController');
});

/** ------------------------------------------
 *  User Routes
 *  ------------------------------------------
 */
Route::group(['prefix' => 'user', 'before' => 'auth'], function()
{

    // User reset routes
    Route::get('reset/{token}', 'UserController@getReset')
    ->where('token', '[0-9a-z]+');
    // User password reset
    Route::post('reset/{token}', 'UserController@postReset')
    ->where('token', '[0-9a-z]+');
    //:: User Account Routes ::
    Route::post('{user}/edit', 'UserController@postEdit')
    ->where('user', '[0-9]+');

    # Admin Dashboard
    Route::controller('/', 'UserDashboardController');
});

/** ------------------------------------------
 *  Frontend Routes
 *  ------------------------------------------
 */
//:: User Account Routes ::
Route::post('user/login', 'UserController@postLogin');

# User RESTful Routes (Login, Logout, Register, etc)
Route::controller('user', 'UserController');

# Index Page - Last route, no matches
Route::get('/', ['before' => 'detectLang','uses' => 'UserController@getIndex']);
Route::post('/', ['before' => 'detectLang','uses' => 'UserController@postIndex']);

Filter:

<?php

App::before(function($request)
{
    //
});


App::after(function($request, $response)
{
    //
});

Route::filter('auth', function()
{
    if (Auth::guest()) {
        Session::put('loginRedirect', Request::url());
        return Redirect::to('/');
    }
});

Route::filter('auth.basic', function()
{
    return Auth::basic();
});

Route::filter('guest', function()
{
    if (Auth::check()) return Redirect::to('/');
});

// Check for role on all admin routes
Entrust::routeNeedsRole( 'admin*', array('admin'), Redirect::to('/') );

// Check for permissions on admin actions
Entrust::routeNeedsPermission( 'admin/blogs*', 'full', Redirect::to('/admin') );
Entrust::routeNeedsPermission( 'admin/comments*', 'full', Redirect::to('/admin') );
Entrust::routeNeedsPermission( 'admin/users*', 'full', Redirect::to('/admin') );
Entrust::routeNeedsPermission( 'admin/roles*', 'full', Redirect::to('/admin') );

Route::filter('csrf', function()
{
    if (Request::ajax()){
        if (Session::getToken() != Request::header('X-CSRF-Token')){
            throw new Illuminate\Session\TokenMismatchException;
        }
    }else if (Session::getToken() != Input::get('csrf_token') && Session::getToken() != Input::get('_token')){
        throw new Illuminate\Session\TokenMismatchException;
    }
});

Route::filter('detectLang',  function($route, $request, $lang = 'auto')
{

    if($lang != "auto" && in_array($lang , Config::get('app.available_language')))
    {
        Config::set('app.locale', $lang);
    }else{
        $browser_lang = !empty($_SERVER['HTTP_ACCEPT_LANGUAGE']) ? strtok(strip_tags($_SERVER['HTTP_ACCEPT_LANGUAGE']), ',') : '';
        $browser_lang = substr($browser_lang, 0,2);
        $userLang = (in_array($browser_lang, Config::get('app.available_language'))) ? $browser_lang : Config::get('app.locale');
        Config::set('app.locale', $userLang);
        App::setLocale($userLang);
    }
});
