My website is http://www.neanderbar.com. The specific page I'm having trouble with is http://www.neanderbar.com/2012/09/ultimate-paleo-crab-cakes-with-avocado-cream/
Before the 3.4.1 update, everything as far as I knew was working fine. Then, after the 3.4.1 update, when I made a new post, facebook would no longer show the "featured image" as part of the post. So, after doing some research, I came across the opengraph settings page and followed some instructions on these forums and made sure that the "post image" tag was set up properly. I ran the debugger, and I got the multiple og:url values error. I have tried reposting, redefining tags, etc, but I am unable to get this error to go away. Facebook also is still not showing the post title or featured image like it used to before the 3.4.1 update.
Thank you in advance for your help.
