[Plugin: Flexo Facebook Manager] fan page and og error

Hi

I have installed the plugin but can’t see where to specify that the posts should be published to my fan page as opposed to my personal wall… can you please tell me how to ensure posts are published on my fan page

Also, when I test the open graph, I get the following errors

Object at URL ‘http://elmurphy.co.uk/2012/05/a-blabbermouth-to-the-

bitter-end/’ of type ‘article’ is invalid because it specifies multiple ‘og:url’ values: http://elmurphy.co.uk/2012/05/a-blabbermouth-to-the-bitter-end/, http://elmurphy.co.uk/2012/05/a-blabbermouth-to-the-bitter-end/.

How do I fix this?
