Note: Recently facebook has released Facebook Api V2 which need to associated business manager account with any app to pull information from a profile. It means facebook now don’t allow directly to pull data from any profile from user name but that user need to connect with this facebook app and facebook provides app specific user information. Example: If I connect facebook from social timeline module then I can show my profile updates, not others, for page it’s not problem. So we added new option in our extension to add page username and profile username. Just keep empty one of those two fields to use one. While you put profile user name don’t write page username, and vice versa. For profile username put same user name who connects the facebook. see this image and how to associated business manager account for your fb app.
