Had the same problem and the solution was to reauthorize the user. Check it here:

<?php

 require_once("src/facebook.php");

  $config = array(
      'appId' => '1424980371051918',
      'secret' => '2ed5c1260daa4c44673ba6fbc348c67d',
      'fileUpload' => false // optional
  );

  $facebook = new Facebook($config);

//Authorizing app:

?>
<a href="<?php echo $facebook->getLoginUrl(); ?>">Login con fb</a>

Saved project and opened on my test enviroment and it worked again. As I did, you can comment your previous code and try.

So I had the same issue  but it was because I was saving the access token but not using it   It could be because I m super sleepy because of due dates  or maybe I just didn t think about it  But in case anyone else is in the same situation   When I log in the user I save the access token    facebook   new Facebook array       appId    gt   lt insert the app id you get from facebook here gt        secret    gt   lt insert the app secret you get from facebook here gt        accessToken    facebook- gt getAccessToken      save the access token for later     Now when I make requests to facebook I just do something like this    facebook   new Facebook array       appId    gt   lt insert the app id you get from facebook here gt        secret    gt   lt insert the app secret you get from facebook here gt        facebook- gt setAccessToken  accessToken    facebook- gt api     insert own code here

Just check for the current Facebook user id  user and if it returned null then you need to reauthorize the user  or use the custom   SESSION user id value - not recommended   require  facebook src facebook php        Create our Application instance  replace this with your appId and secret    facebook   new Facebook array     appId     gt   APP ID      secret    gt   APP SECRET         user    facebook- gt getUser      photo details   array  message    gt   my place     file  photos my jpg     Example image file  photo details  image           realpath  file    if   user      try          We have a valid FB session  so we can use  me       upload photo    facebook- gt api   me photos    post    photo details       catch  FacebookApiException  e        error log  e              login or logout url will be needed depending on current user state  if   user       logoutUrl    facebook- gt getLogoutUrl      else      redirect to Facebook login to get a fresh user access token    loginUrl    facebook- gt getLoginUrl      header  Location       loginUrl       I ve written a tutorial on how to upload a picture to the user s wall

I have got the same issue when tried to get users information without auth   Check if you have loggen in before any request     uid    facebook- gt getUser      if   uid          me    facebook- gt api   me         The code above should solve your issue

After a certain amount of time  your access token expires   To prevent this  you can request the  offline access  permission during the authentication  as noted here  Do Facebook Oauth 2 0 Access Tokens Expire
