Question

I have the following feed dialog code. Users report me that they are unable to share but from my machine even using different browsers without any history it works perfectly. What could the problem be? What’s a good checklist to debug this problem?

FB.init({appId: "1111", status: true, cookie: true});

function postToFeed(description) {

  var obj = {
    method: 'feed',
    link: 'http://example.com/',
    picture: 'http://example.com/static/facebook-app-icon.png',
    name: 'Example app',
    caption: 'Example caption!',
    description: description
  };

  FB.ui(obj);
}

<div id='fb-root'></div>
<a onclick="var msg=getShareMsg(); postToFeed(msg); return false;">
    <img src='/static/facebook.png' alt="Share" title="Share on Facebook">
</a>

Answer 1

Firstly, are they getting the popup with an error message, or nothing at all?

If it’s nothing at all:

• Is it a Javascript error on their end (Check the JS error console)
• Are popups being blocked on their machines that you have allowed? This will happen if there is no user event triggering the popup

If it’s the FB popup with an error:

• Is the app in sandbox mode and are you the only developer? Check (https://developers.facebook.com/apps//summary)
• Has the FB JS SDK loaded correctly? How you are including the ‘//connect.facebook.net/en_US/all.js’ file?
