花式盒形式没有弹出

Question

我是这个网站的新手所以请原谅我。这是我的表单代码。它突然冒出来了。突然间它停了下来。我们确实有ReCaptcha但我们可以在没有它的情况下提交表格。所以我们刚刚删除了recaptcha。

<form id="emailform" name="emailform" method="post" action="/post-email.php"     onSubmit="return ValidateRequiredFields();">
    <table width="100%" border="0" cellspacing="10" cellpadding="0" style="margin-left:20px" align="left">
        <tr>
            <td width="31%" align="left">Full Name:</td>
            <td width="69%" align="left">
                <label>
                    <input type="text" name="first_name" id="fname" />
                </label>
            </td>
        </tr>
        <tr>
            <td align="left">Email:</td>
            <td align="left">
                <label>
                    <input type="text" name="email2" id="email2" />
                </label>
            </td>
        </tr>
        <tr>
            <td align="left">Confirm Email:</td>
            <td align="left">
