To get an App ID and App Secret you have to create a Facebook application
You have to fill in the following:
App Name: Anything you like, will appear as “via …” below the message
Website > Site URL: http://XXXXXXXXXXXXXX
Click here to create and navigate to ‘Apps’ and then to ‘Create New App'”
Whaaaaat? So i have to create an app to get an App ID before i can install “Add Link to Facebook” I went ahead and tried but dont know what to do.
