php - 图像文件成功上传到本地主机，但它不能在使用 CI 的服务器中

Question

当我尝试在本地主机上上传图像文件时，它存储在数据库中，我可以读取上传的图像，但是当我通过 FTP 将代码上传到服务器时，它显示如下错误:

• This page isn’t working
• blablabal.com is currently unable to handle this request.
• HTTP ERROR 500

那是因为我在 localhost 中的 php 版本与服务器上的 PHP 版本不同吗？

有人能帮我吗？谢谢大佬

我的 Controller

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class News extends CI_Controller {
function __construct() {
    parent::__construct();
    $this->load->model('news_model');
        $this->load->helper(array('form', 'url'));
    $this->load->library('session');
}

    public function index()
{
$data['datax'] = $this->news_model->tampil_data()->result();
$data['viewx']="news/content";
$this->load->view('template/header');
$this->load->view('template/main',$data);
  //$this->load->view('news/content');
  $this->load->view('template/footer');
}

    function tambah(){
$data['title'] = "Tambah news";
$data['updateid'] = '';
$data['update'] = '';
$data['viewx']="news/form";
$this->load->view('template/header');
$this->load->view('template/main',$data);

  $this->load->view('template/footer');

    }

    function tambah_aksi(){

        $config['file_name'] = $nmfile; //nama yang terupload nantinya
        $this->upload->initialize($config);

        if($_FILES['images']['name'])

我以前遇到过同样的问题，我已经找到了解决方案 我已经用我的旧 ci 版本 3.0.4 替换了我当前的 system/libraries/upload.php 文件
