JSON成功/错误消息显示在本地服务器上但不在godaddy服务器上

我的本地服务器上有PHP 5.4.45，Godaddy服务器上有PHP 5.4.45 .

contact_p.php 页面正确发送 contact.php 表单页面上输入的所有有效/无效数据的所有成功/错误消息 . 所以我可以在 contact.php 页面上打印它们 .

联系人查询已成功插入本地和godaddy服务器上的数据库表中，但成功/错误消息仅显示在我的本地Web服务器上，而不显示在GoDaddy服务器上 .

那么这个奇怪问题可能是什么原因呢？请注意，我可以在我的脚本和/或服务器上进行必要的更改 .

contact.php

<form name="contactForm" id="contactForm" novalidate>
<div class="control-group form-group">
    .
    .
    other fields like Name, Mail, Phone, captcha etc

    .
    <div id="success"></div>
    <!-- For success/fail messages -->
    <button type="submit" class="btn btn-primary">Send Message</button>
