Codeigniter: Cannot modify header information - headers already sent by

我正在将我的网站转移到网上，但是当我编辑我的表数据时，我遇到了这样的错误，

A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/shintiad/public_html/sociotraveler/application/views/template/index.php:20)
Filename: libraries/Session.php
Line Number: 688

我的模板/索引.php代码

<!DOCTYPE html>
<html lang="en">
  <head>
        <!-- Meta -->
        <?php $this->load->view('template/partial/meta');?>
        <!-- Meta -->
  </head>
  <body>
        <!-- Header -->
        <?php $this->load->view('template/partial/sidebar');?>
        <!-- Header -->
        <!-- Dynamic Content -->
        <div class="content">
        <?php $this->load->view("{$page_info->content}");?>
        </div>
        <!-- Dynamic Content -->
        <!-- Footer -->
        <?php $this->load->view('template/partial/footer');?>
        <!-- Footer -->
   </body>
  </html>

当我在我的本地主机上运行它时，一切都很好。请帮忙，谢谢...*我之前检查过空格

请检查所有PHP文件并删除<?php标记之前的空格。如果有空格或换行符，则会启动 http 请求的正文，并且无法向 http 请求添加新标头。
