[Plugin: WP Facebook Open Graph protocol] Invalid FB Admin value

How do I fix this error? I’ve tried the fbid for my personal page and business page. Neither one works.

Errors That Must Be Fixed
Object Invalid Value: Object at URL ‘http://sgoodwinart.com/’ of type ‘website’ is invalid because the given value ‘256201747827917’ for property ‘fb:admins’ could not be parsed as type ‘fbid’.
