Laravel 5类管理员不存在

Laravel 5和这个管理类有问题，问题是所有东西都在本地主机上工作，现在我在服务器上部署了它（做了很多修复，但没有触及这个）后，它就不工作了。

当我转到页面"/medice"时，错误就会出现，管理员应该可以看到该页面。

错误：

AdminController位置（App/Http/Controllers/）：

<?php namespace App'Http'Controllers;
use App'Post;
use App'Http'Requests;
use App'Http'Controllers'Controller;
use Illuminate'Http'Request;
class AdminController extends Controller {
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        $posts = Post::oldest()->where('status', '=', '0')->get();
        return view('admin.index', compact('posts'));
    }
    /**
     * Show the form for creating a new resource.
     *
     * @return Response
     */
    public function trash()
    {
        $posts = Post::oldest()->where('status', '=', '2')->get();
        return view('admin.trash', compact('posts'));
    }
    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function changeStatus($id, $status)
    {
        $post = Post::findOrFail($id);
        if($post->status != $status){
            $post->status = $status;
            $post->save();
        }
        return redirect('/moderate');
    }

}

路线：

// Admin only
Route::group(['middleware' => ['auth', 'admin']], function()
{
    Route::get('/moderate', 'AdminController@index');
    Route::get('/posts/{id}/status/{status}', 'AdminController@changeStatus');
    Route::get('/trash', 'AdminController@trash');
});
