Notice: Trying to get property of non-object in /home2/hosting_users/beop07/www/tbmanifesto/twitter.php on line 116

Warning: Invalid argument supplied for foreach() in /home2/hosting_users/beop07/www/tbmanifesto/twitter.php on line 116

이렇게 오류가 납니다.
line116은 foreach ($twitter_data->statuses as $i => $value) 요부분입니다.
트위터 api 관련해서 실시간으로 뿌리는거 하는건데 foreach 부분에서 오류가 나네요..

저오류 관련해서 간단한 힌트라도 알려주시면 감사하겠습니다.
