I created a web page to login to Facebook and then once logged in, create a session which stores the access token and also the user id. And then I redirect the user to a profile page where it pulls the information from user's facebook posts via a Graph API call and then presents the information. I'm using PHP to get the Graph API.
It's working fine on my local machine and I can see the data just as I want. But when I access the same link from outside my home network, It displays a blank page. I can still login from outside the home network so that piece of code works fine, but it is unable to pull the user_posts. There's nothing wrong with the code as far as I understand otherwise I won't be able to access the link even from my local network.
I tried many different solutions, added a whitelist of IPaddresses (but it may be that I'm not adding them in the correct place). I'm at a total loss. Has someone experienced a similar situation? If adding the specific ip addresses would help, where do I add them exactly. There are so many confusing fields in the Facebook developers settings.
Any help is much appreciated.
