Файловый менеджер Unisharp laravel NotFoundHttpException

Я просто использую Вариант 2: TinyMCE4

затем измените path_absolute : "/", в path_absolute : "{{ URL::to('/') }}/",

в основном вот весь мой код …

@extends('layouts.app')

@section('content')
<div class="container top-space">
<div class="row" >
<div class="container weldiv">
