加载数据库时出现Codeigniter空白页

Question

因此，在搜索stackoverflow之后，决定写这个问题。

这次我正在研究Godaddy的托管cPanel计划。 上传了一个干净的Codeigniter V 2.2.6程序包，并显示了欢迎消息。 我用正确的连接数据用url和database.php配置了config.php。 到现在为止，一切都按预期进行。 因此，在加载数据库后，看看是否一切都变了，如果刷新页面，则会出现“黑屏死机”。

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

class Welcome extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *      http://example.com/index.php/welcome
     *  - or -  
     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in 
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $this->load->database();
        $this->load->view('welcome_message');
    }
}

/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */

因此，在搜索中断处之后，我在第300行的/system/core/Codeigniter.php中找到了该行。在$ CI = new $ class（）之前中断；

/*
 * ------------------------------------------------------
 *  Instantiate the requested controller
 * ------------------------------------------------------
 */
    // Mark a start point so we can benchmark the controller
    $BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_start');
    $CI = new $class();

在日志文件中，返回以下行

我需要部署在其他服务器上制作的网络，并且当我在Godaddy中上载时，出现空白页，这就是我上载干净的Codeigniter程序包的原因。 有人可以帮助我吗？ 提前致谢。

编辑忘记在index.php上写错误报告

define('ENVIRONMENT', 'development');

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            ini_set('display_errors',1);
            error_reporting(E_ALL);
        break;

        case 'testing':
        case 'production':
            error_reporting(0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

将数据库库加载到application / config / autoload.php中，如下所示：

$autoload['libraries'] = array('database');

从文件中删除以下行：

$this->load->database();
