Codeigniter 文件上传 - IIS 7.5 HTTP 错误 500.0

Question

我似乎在CodeIgniter 中上传文件时遇到问题，导致标题中出现错误。我在不同网站上的同一台服务器上进行文件上传，这就是为什么我认为相同的代码可以用于此上传。我第二次尝试upload时出现问题。

这是我目前在controller 中使用的代码

public function bulk_product_upload_file()
{
    $location_of_bulk_product_files = LOCATION OF FOLDER;
    if ($this->is_post()):
        if (is_uploaded_file($_FILES['userfile']['tmp_name'])):
            $date_for_file = date("dmyHis");

            $config['upload_path'] = $location_of_bulk_product_files; //upload directory
            $config['allowed_types'] = 'xlsx'; // allowed file types
            $config['max_size'] = '100';
            $config['overwrite']  = TRUE;
            $config['remove_space']  = TRUE;
            $config['file_name'] = $date_for_file;
            $this->load->library('upload', $config);

            if($this->upload->do_upload()):
            // I have also tried if($this->upload->do_upload('userfile')): that resulted in the same error
                // file upload success
            else:
               // file upload failed
            endif;
        else:
            $this->session->set_flashdata('message_error','Please select a file to upload.');
            redirect('main/create_bulk_product');
        endif;
    else:
        $this->session->set_flashdata('message_error','Sorry! Somthing went wrong, please try again.');
        redirect('main/create_bulk_product');
    endif;
}

我收到的error： HTTP Error 500.0 - Internal Server Error The page cannot be displayed because an internal server error has occurred. Module FastCgiModule Notification ExecuteRequestHandler Handler PHP Error Code 0x00000000

我更感到困惑的是，它正在同一服务器上的另一个网站上运行，但不是这个。所有设置似乎也完全相同。任何帮助将不胜感激。

问题在于 CodeIgniter 本身。 3.1.2 上传库有问题。
