php联系表单不会转到收件人电子邮件

Question

我的网站上有一个PHP联系表格，上周正在运行，我今天去试用它，现在不是。我把联系表单放在网站上的几页上，这会有问题吗？我现在已经从FTP删除了我的联系表单所在的所有其他页面，看看这是否是一个问题，但它仍未通过收件人电子邮件发送。

<form action="bat/MailHandler.php" method="post" form id="contact-form" class="contact-form">
                      <div class="success"> Contact form submitted! <strong>We will be in touch soon.</strong> </div>
