I am having this same issue, but a tad different. Running 3 sites on 1 host, and trying to push each to their FB page. The main site posts fine, yet the other 2 do not. We purchased the full version to support and hopefully solve this issue, but alas they are still not posting to the other 2 FB pages. Completely deleted/re-setup all free versions and FB apps just in case, yet still no luck.
The really weird thing is I can see each individual test post across all 3 pages from the computer I post them from, yet no other device can see them (verified not a browser cache issue).
