Login with facebook appears as regular text and not a link.

I've installed the plugin and it works great on the login and register pages. Great plugin by the way! The only part where it doesn't seem to be thoroughly perfect on my site (I've seen it working on others) is that the facebook connect widget displays TEXT "login with facebook" instead of the button which actually logs you in. Does anyone know what may be causing this?
