Latest tweets not working?

I’m having difficulty getting the tweets to show up. I don’t think it’s CSS – when I view source, I’m just getting text that says, “Over a year ago.”

Tried this in a post here: http://mav.cajohnsononline.com/test/

And in a widget on the home page: http://mav.cajohnsononline.com/

The Twitter account is https://twitter.com/MaverikLacrosse/.

Any ideas?
