We've had numerous support queries regarding allArticleAnnounce and errors on connecting to a Facebook page.
From our investigations thus far, it appears that a change has been made in the way Facebook's API works, particularly with how apps like allArticleAnnounce get permission to publish to Pages other than the user's profile.
We're working on a fix, and will let you know as soon as we know more or when we've found a solution.
This is only affecting new installations of allArticleAnnounce, so if you have already successfully connected allArticleAnnounce from your website to Facebook, you will be unaffected.
