[Plugin: WP Facebook Open Graph protocol] Link to wrong page

Whenever I link my blog page into FB it redirects to my home page instead of the blog page.How do I fix this?

Here’s the error:
Redirect Path
original: http://www.sgoodwinart.com/blog
301: http://sgoodwinart.com/blog/
og:url: http://sgoodwinart.com/
Final URL is in bold (this is the URL we tried to extract metadata from).
