It resolves fine for me, but then again, I'm logged into my own FourSquare account. There's a possibility that because of my privacy settings you'd need to be connected to me on the service to be able to see the posts there. I was pretty sure that my settings were all public, but perhaps not?

OwnYourCheckin, while relatively nice, doesn't integrate very well with WordPress. I'd recommend using OwnYourSwarm instead, though some have reported some minor issues in getting it set up with WordPress. I'm hoping to have time to switch over to it shortly myself.
