Twitter Feed Not Showing Up

On my website, I set-up a widget in the sidebar to display an image and my most recent Twitter post. When I first got it set-up it worked fine. I have not made any changes to the code, but now the most recent Twitter post is not showing up.

Below is the code I am using.

Any suggestions?

Thanks,
