Bloody stupid AWS, bloody stupid Facebook and bloody stupid me!

Well, it's been nearly 2 years. And i haven't been sitting around doing nothing, i've been starting startups and coding like crazy to get some awesome stuff launched. Unfortunately, now i've encountered an issue, where my app no longer talks to facebook, and nothing is telling me what's wrong! At this point, i'm assuming is due to an update from php 5.4 to 5.5, but i am absolutely screwing, as i can't roll back the update! Lamey lame. Anyway, rant over, kthxbai
