Plugin has stopped working

Hi there,

I love this plugin, but this morning, I noticed it’s stopped working as it should.

If you scroll to the bottom of this website, you’ll see the Gravatars of the authors appearing ok:

http://www.warpaintmag.com/

However clicking one of them no longer takes me to the authors page, but instead shows the banner adverts area from the sidebar zoomed in and filling the page (which is pretty weird!)

Any idea what is causing this?

Thanks!
