Примечание: попытка получить свойство необъектного Twitter API

Я использую Twitter API, чтобы получить твиты на веб-сайте, иногда это показывает, хорошо, а затем вдруг перестает показывать ошибку ..

Эта ошибка возникает, когда перестает работать:

Notice: Trying to get property of non-object in public_html/wp-content/themes/sandra/TwitterModel.php on line 26

Вот мой код:

require("TwitterModel.php");
$tw = new TwitterModel();
$t = $tw->getTweets("sandrasflower");
echo "<div>";
foreach($t['tweets'] as $date=>$tweet)
{
echo "<div class='tweet'>";
echo $tweet . "<br />" . date("jS F Y", strtotime($date));
echo "</div>";
}

Пожалуйста, помогите мне кто-нибудь …

Код файла TwitterModel.php:
