I had a look at your site, and you seem to be using 2 different plugins (or a plugin and a function in your theme) to add Open Graph meta tags to your site.
Unfortunately, duplicate Open Graph tags create errors on Facebook's end, and cause Publicized posts to be rejected:

Could you try to deactivate one of the Open Graph plugins, until errors disappear from Facebook's Debugger? Once you've done so Publicize should start working again.
I hope this helps.
