Codeigniter 电子邮件类不起作用

我正在尝试 Codeigniter 电子邮件类，但它不起作用，或者可能是我在配置或其他方面犯了错误。请修复它并告诉我我应该做什么。我在使用 codeigniter 电子邮件类时遇到问题。

这是将表单数据发送到控制器后的屏幕截图。

看法：

                <h4>Send Your Feedback</h4>
                <form action="<?php echo base_url('front/feedBack') ?>" enctype="multipart/form-data" method="post" class="form-horizontal">
