if someone is still banging their head over this here is what is wrong now. I was hired to fix this mess!

1. Check App domain in fb panel , must match with the domain where your app is.

2. edit base_facebook.php find:

   public function getAccessToken() {

   if ($this->accessToken !== null) {
     // we've done this already and cached it.  Just return.
     return $this->accessToken;
   }
   
   // first establish access token to be the application
   // access token, in case we navigate to the /oauth/access_token
   // endpoint, where SOME access token is required.
   $getApplicationAccessToken = $this->getApplicationAccessToken();
   $this->setAccessToken($getApplicationAccessToken);
   $user_access_token = $this->getUserAccessToken();
   if ($user_access_token) {
     $this->setAccessToken($user_access_token);
   }
   return $this->accessToken;
   

   }

to::

  public function getAccessToken() {

    if ($this->accessToken !== null) {
      // we've done this already and cached it.  Just return.
      return $this->accessToken;
    }

    // first establish access token to be the application
    // access token, in case we navigate to the /oauth/access_token
    // endpoint, where SOME access token is required.
    $getApplicationAccessToken = $this->getApplicationAccessToken();
    $this->setAccessToken($getApplicationAccessToken);
    $user_access_token = $this->getUserAccessToken();
    if ($user_access_token) {
      //$this->setAccessToken($user_access_token);
    $this->accessToken = $user_access_token; //edit; msolution
    }
    return $this->accessToken;
  }

3. Next find the function: getAccessTokenFromCode()

find the line:

parse_str($access_token_response, $response_params); 

replace it with:

//parse_str($access_token_response, $response_params); //edit:: msolution;;
$response_params = json_decode($access_token_response, true );

commenting the original and adding json_decode

thats it!
