Facebook added the ability for users to browse using a secure connection (or https connection) back in January, but unless you were reading their blog or Mashable most users probably didn’t notice. This important feature secures the communication between your browser and Facebook’s servers as you browse the site, closing a gaping security hole that allowed anyone to easily hijack your session and pretend to be you while sitting at the coffee shop. Previously you had to dig deep into account settings to find and turn on https browsing, but recently Facebook has been promoting this feature with a large message on users’ news feeds.

This additional promotion means that more and more Facebook users will turn this setting on for their accounts. Great news… isn’t it?

Of course, better security for users is great but this change could completely break parts of your business’ Facebook page. Facebook tabs or applications that contain unsecure (non-https) content will not display to these users, and instead a large error message displays. The message gives them the option to temporarily disable secure browsing (that certainly sounds ominous) or else they can’t see this content.

Depending on what part of your page is causing the issue, the fix could be as easy as changing or adding one setting and loading an SSL certificate to the site where you’re hosting your app or external content (if you don’t already have one).

You’ve put a ton of effort into using social media as a marketing tool for your business, now make sure to take five minutes to change that setting and test your page to make sure all your fans actually get to see it.
