有时我的网站，其fb sdk被重定向到奇怪的网址

Question

有时我网站中的用户会被重定向到这样的奇怪网址：https://connect.facebook.net/help/contact.php?show_form=post_problem。

我查了一下，网站已经嵌入了这样的fb sdk：

<script src="https://connect.facebook.net/signals/config/<key>?v=2.8.12&amp;r=stable" async=""></script>

<script async="" src="https://connect.facebook.net/en_US/fbevents.js"></script>

<script>
!function(b,e,f,g,a,c,d){b.fbq||(a=b.fbq=function(){a.callMethod?a.callMethod.apply(a,arguments):a.queue.push(arguments)},b._fbq||(b._fbq=a),a.push=a,a.loaded=!0,a.version="2.0",a.queue=[],c=e.createElement(f),c.async=!0,c.src=g,d=e.getElementsByTagName(f)[0],d.parentNode.insertBefore(c,d))}(window,document,"script","https://connect.facebook.net/en_US/fbevents.js");fbq("init","my id");fbq("set","agent","tmgoogletagmanager","some value");fbq("track","PageView");
</script>

有没有人有同样的问题？我仍然无法弄清楚它在何处触发重定向...
