Site no longer secure after 4.2.2 update

I have just updated to WordPress 4.2.2 and now my website pages are showing a grey padlock with the triangle within it. Nothing else has changed. I notice in my page source this:
?></title>
<link rel=”profile” href=”https://gmpg.org/xfn/11&#8243; />

Any idea what this http address is?

Please check my site:

Thanks in advance for any help…
