I have WordPress 3.4 and my plugin version is 1.3.3
I found that it worked well when I add user as admin, but didn’t discover my application.
After fast check in code I found that you send a ‘key’ get parameter to your app. The problem is that the get parameter is ?key=https://THE_KEY_VALUE and that extra ‘https://’ is the devil. In return URL from your site this ‘https://’ is given back, but it doesn’t match (of course) the key from database.
I don’t have time now to dig deeper into this problem.
Thanks for the great plugin !
@ the other reporters – there is a fast workaround for this prbolem:
1. Click on the link to take facebook apps
2. When your page is reloaded check the URL in your browser address bar. It shall contain ?page=wpseo_social&key=https://XXXXXXXXX
3. Delete this extra https:// after &key= , but keep everything else
4. Press ENTER to load the edited URL
5. You shall see a new select box with your application
