title: The site uses SSL, but Google Chrome has detected insecure content on the page
body: <p>I'm using SSL on my website and it is giving me the <a href="https://support.google.com/chrome/bin/answer.py?hl=en&amp;answer=95617" rel="noreferrer">lock with yellow triangle icon</a> ("The site uses SSL, but Google Chrome has detected insecure content on the page.")</p>
  
  <p>On clicking the lock icon it says:</p>
  
  <blockquote>
    <p>Your connection to domainname is encrypted with 256-bit encryption. However, this page includes other resources which are not secure. These resources can be viewed by others while in transit, and can be modified by an attacker to change the look of the page. The connection uses TLS 1.0. The connection is encrypted using AES_256_CBC, with SHA1 for message authentication and DHE_RSA as the key exchange mechanism. The connection is not compressed.</p>
  </blockquote>
  
  <p>How do I ensure I get the green lock?</p>
