Only the same Facebook user can see the comments

Can you post a URL this happens on? There's a few possible causes, but if we see (and test) on the page, it should help us give the best solution.

Thanks,

Coolios,
It's impossible to be 100% certain on this, but the most likely reason that only the user that posted the comments can see them is because your site is completely restricted. Facebook needs to be able to scan the pages that comments are posted on so that it can determine that the site isn't spammy, malware, or other 'bad' material. Once they've scanned a few pages from your site, they'll mark the whole thing as 'good', and things should act just fine then. Until your site (or parts of it) are public though, you'll be in a very restricted mode from Facebook.

Hope that makes sense, but let us know if you have any other questions.

Thanks,
Alex

Lots of things happen when Facebook can't see your site. If you add a Like button, you'll likely get messages that the URL is unreachable. Until Facebook can scan the page, it's really up to them as to how they want to restrict things, and comment restrictions has been mentioned in the past, but it's never been a steady problem after the site's gone live.

Good luck,
Alex
