Facebook驗證問題，500服務器erorr

從昨天我的網站從Facebook服務器端獲取500服務器錯誤，同時嘗試登錄到該網站，我確定我沒有做任何更新我的代碼，我搜索了一切，但沒有找到任何解決方案。請檢查我的代碼並幫助我。Facebook驗證問題，500服務器erorr

    } else {

    $login_url = $facebook->getLoginUrl(array('scope' => 'email,publish_stream')); 
    header("Location: " . $login_url); 
} 
?>

我附上了所有的代碼。請幫我分類這個問題。謝謝。

錯誤數字輸出！問題不在於此代碼。在facebook設置頁面中，我發現APP ID之前有一個空格。它現在修復.. Facebook dosent修剪或刪除空白獲取身份驗證中的參數。如果有一個無效字符，它會在facebook中獲得500服務器錯誤。我認爲這是一個嚴重的安全問題。 Hal Rotholz - 謝謝你的線索..
