good morning, I have a problem, I create an app in my facebook profile where I am administrator of several pages of facebook, the problem is basically when I want to run the Ultimate Facebook plugin on my wordpress page, configure the app id and secret but when I to authorize to run this app on page no adds. Change the method of authorization in facebook? 'll be mistaking the steps? It could happen the user and pass of my wordpress site and my facebook to help me run this app on facebook page so that the ads are loaded automatically when post them on facebook wordpress.
Thank you very much, I hope news
