Chrome中的EV SSL错误“不安全<表单>调用”

I have installed EV SSL on my site. But in chrome it isnt showing any padlock sign.

i checked the site for ssl scan here and it is giving error

Insecure < form > call. Found on line # 2243 in file: www.smartteck.co.uk/index.html

but i can not figure out what is on ine 2243 the only form i have is newsletter signup in my footer and i can not see any problem with that.

can any one tell me what is wrong there?

my newsletter code:

<div id="subscribe-form" class="clearer">
    <form action="<?php echo $this->getFormActionUrl() ?>" method="post" id="newsletter-validate-detail">
        <div>
            <label for="newsletter"><?php echo $this->__('Newsletter') ?></label>
            <div class="input-box">
                <input type="text" name="email" id="newsletter" title="<?php echo $this->__('Sign up for our newsletter') ?>" class="input-text required-entry validate-email" />
            </div>
            <button type="submit" title="<?php echo $this->__('Subscribe') ?>" class="button btn-inline"><span><span><?php echo $this->__('Subscribe') ?></span></span></button>
        </div>
    </form>
</div>
<script type="text/javascript">
//<![CDATA[
    var newsletterSubscriberFormDetail = new VarienForm('newsletter-validate-detail');
    new Varien.searchForm('newsletter-validate-detail', 'newsletter', '<?php echo $this->helper('newsletter')->__('Enter your email address') ?>');
//]]>
</script>

Thanks in advance.

You have a <form-tag which has an action which a hard-coded http://-URL as destination (action). I suppose Chrome does not show the padlock as users using this form will be redirected from https to http loosing their privacy.

Open the web console in Chrome to see any warning there.

Change http to https in <form id="newsletter-validate-detail" method="post" action="http://www.smartteck.co.uk/newsletter/subscriber/new/"> or use a protocol agnostic form: <form id="newsletter-validate-detail" method="post" action="//www.smartteck.co.uk/newsletter/subscriber/new/"> which will work for http and https.
