Facebook test user error validating application
While loggedin to your Facebook account go to Facebook Developers page. New modal window will show, enter your Application display name, category and click “Create App” button. At the top of the page you should be able to find App ID and App Secret keys (we will be using them a bit later).
Enter your App ID and App Secret keys generated earlier, save the form and (after page reload) click “Connect with Facebook” link. After successful authentication you should be redirected back to your site, where from the list you will be able to select to which account you wish to post updates (the list will allow you to select either your personal account or one of Pages to which you are assigned as an Administrator). Finally you will be presented with some automatic shares default parameters that will allow you to customize your FB shares, set them as you see fit and again save the form (you will be able to edit this at any time).
At the bottom of the configuration form “Send Test Share” button, once you finished your configuration it is recommended to use it in order to verify if your application is working as expected.
