Facebook not showing to anyone

Hello –
Revive Old Post is working great with TWitter, and is also appearing to work on Facebook. However, each post to Facebook shows the word “Array” at the end of the post, and it is not shown to anyone but me (so, where you can see people served the post, it’s only 1 – and that’s me). Is this a common error? Thank you!
Megan
