联系表格7不发送每次提交

我在wordpress网站上使用联系表格7 . 我遇到的问题是，有时联系表单不会将输入发送到我的电子邮件 . 无论邮件是否发送，我都使用Flamingo来保存所有输入 . 但即使这样，也不是每个联系表都被保存了..

这是网站：link

我的代码可能有问题吗？我复制了联系表格7的全部代码，将其放入幻灯片中 .

这是我在幻灯片中使用的代码：

<div class="wpcf7" id="wpcf7-f16687-p16471-o1" dir="ltr" lang="en-US">

<div class="screen-reader-response"></div>
  <form name="" action="/register" method="post" class="wpcf7-form default"  novalidate="novalidate">
 <div style="display: none;">
  <input name="_wpcf7" value="16687" type="hidden">
  <input name="_wpcf7_version" value="4.1" type="hidden">
  <input name="_wpcf7_locale" value="en_US" type="hidden">
  <input name="_wpcf7_unit_tag" value="wpcf7-f16687-p16471-o1" type="hidden">
  <input name="_wpnonce" value="73278d464f" type="hidden">
</div>

<p>Team players<br>
<span class="wpcf7-form-control-wrap players"><textarea name="players" cols="40" rows="10" class="wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required" aria-required="true" aria-invalid="false"></textarea></span> </p>
<p><input value="Send" class="wpcf7-form-control wpcf7-submit" type="submit"><img style="visibility: hidden;" alt="Sending ..." src="http://beeverlyfields.com/wp-content/plugins/contact-form-7/images/ajax-loader.gif" class="ajax-loader"></p>

<div class="wpcf7-response-output wpcf7-display-none"></div></form>

</div>

我已经更改了联系表单7中的“收件人”和“发件人”字段，就像其他一些主题中所建议的那样 .
