This plugin somehow didn't work in my site. I have configured everything from the App ID, creating new social content locker, copying the shortcode to my post, add something in between the shortcode for it to be hidden, and everything...
But it turned on that the button doesn't appear, so nobody can like my page or tweet it or google plus it.
I'm using W3 Total Cache, if that probably is the problem, and I'm using the latest version of the free plugin.
The page that I want to lock is here: http://www.syamsulalam.net/faktor-ranking-seo-2013/
The shortcode is embedded, but somehow it won't appear in my post.
