無法從數據庫中刪除行

我想從我的表中刪除一些行。但是，當我點擊刪除，這只是給我一個空白頁面。我很確定id值和我的db連接。無法從數據庫中刪除行

這是我的代碼：

// connect to the database 
include('connect-db.php'); 

// confirm that the 'id' variable has been set 
if (isset($_GET['id']) && is_numeric($_GET['id'])) { 
    // get the 'id' variable from the URL 
    $id = $_GET['id']; 

    // delete record from database 
    if ($stmt = $mysqli->prepare("DELETE FROM my_table WHERE id = ? LIMIT 1")) { 
     $stmt->bind_param("i",$id); 
     $stmt->execute(); 
     $stmt->close(); 
    } else { 
     echo "ERROR: could not prepare SQL statement."; 
    } 
    $mysqli->close(); 

    // redirect user after delete is successful 
    header("Location: Dashboard.php"); 
} else { 
    // if the 'id' variable isn't set, redirect the user 
    header("Location: Dashboard.php"); 
}
