Plugin not publishing to profile

I’ve recently installed 1.1.10 and created a corresponding facebook app. It will publish posts to my facebook artist page but shows the following error when trying to post to my profile:

Failed posting to your Facebook Timeline. Error: {“message”:”Object at URL ‘http://deejaycomic.com/2012/12/30/testing-2/’ of type ‘article’ is invalid because it specifies multiple ‘og:url’ values: http://deejaycomic.com/2012/12/30/testing-2/, http://deejaycomic.com/2012/12/30/testing-2/.”,”type”:”Exception”}

Hoping this is just user error on my end, but I can’t figure out why. Thanks in advance for any help!
