Thanks for sending the link by Private Message. Looking at that page, my best guess is that the og:image tag is causing issues. When looking at the Facebook Linter tool, Facebook is actually reporting that the page can't be reached:
developers.facebook.com/tools/lint
Since I can reach it, I don't think that's the problem, but obviously check to see if all of your pages are showing this. If other pages work, then look at the image tag on that page. JFBConnect is likely pulling the first article image, but it has spaces in the name, which isn't proper form for an Internet image. Can you try changing that image to not have spaces, and then use the linter again.
Hopefully, that's all there is to it, but if that doesn't work, just let us know. Also, can you tell me if this is the only (or one of a few pages on your site) with this issue, or is it on every single page?
Thanks,
Alex
