You will notice that the “view app profile page” link on the bottom left side is missing. If you can not get to the profile page, this also means you can not click on the “add to my page” link. As far as we know and hope, this is a Facebook bug. We know that Facebook is claiming they will be removing the profile pages on February 1st, so hopefully this is just a temporary issue and there will be a new easier way to add your app to your fan page in the upcoming future. For now we have found a temporary fix!!
