Hey everyone! I encountered an error in this particular piece of code, below is the error message. All my other website's code works fine except doEditAccount.php.

以下是我的代码：Account.php：

//User can choose to edit or delete their account here session_start(); include_once("linkConnection.php"); include_once("navbar.php"); include_once("session.php"); if(isset($_SESSION['userId'])){ $userId=$_SESSION['userId']; $query="SELECT * FROM users WHERE userId = $userId"; $Result=mysqli_fetch_assoc(mysqli_query($link,$query)); echo " 
Username : ".$_SESSION['username']; echo "

Account.php form input will be passed to doEditAccount.php, below is the code.

error_reporting(E_ALL); ini_set('display_errors', '1'); include_once("linkConnection.php"); include_once("navbar.php"); include_once("session.php"); if(isset($_POST['edit1'])){ }else{ } // $_SESSION['Cmsg'] = Customization Message if (isset($_POST['edit2'])) { if (isset($_POST['color'])) { $plaincolor = $_POST['color']; setcookie("lv5BG", "", time() - 3600); // Remove lv5BG cookie if it exists setcookie("lv10BG", "", time() - 3600); // Remove lv10BG cookie if it exists setcookie("plaincolor", $plaincolor, time() 60 * 60 * 24 * 365 * 10); $_SESSION['Cmsg'] = "You have successfully changed background to $plaincolor."; } elseif (isset($_POST['lv5BG'])) { $lv5BG = $_POST['lv5BG']; setcookie("plaincolor", "", time() - 3600); // Remove plaincolor cookie if it exists setcookie("lv10BG", "", time() - 3600); // Remove lv10BG cookie if it exists setcookie("lv5BG", $lv5BG, time() 60 * 60 * 24 * 365 * 10); $_SESSION['Cmsg'] = "You have successfully changed background to $lv5BG."; } elseif (isset($_POST['lv10BG'])) { $lv10BG = $_POST['lv10BG']; setcookie("plaincolor", "", time() - 3600); // Remove plaincolor cookie if it exists setcookie("lv5BG", "", time() - 3600); // Remove lv5BG cookie if it exists setcookie("lv10BG", $lv10BG, time() 60 * 60 * 24 * 365 * 10); $_SESSION['msg'] = "You have successfully changed background to $lv10BG."; } else { $_SESSION['Cmsg'] = "You have submitted nothing. No change to customizations."; } header('Location : Login.php'); } ?>

Login.php:

        
    
 
 
  
 
Login Page :
  Your Username: 
  

  Your Username: 
   Your Password: 
  

 Remember Me Forget Password

然后我重定向到Login.php，让用户看到他们更新的背景。问题是，当我点击“确认更改”按钮时，它给我显示之前在doEditAccount.php网站上提到的错误，除此之外，我的其他网站都能正常工作。有什么问题的想法吗？

我以为是重定向的问题，所以尝试删除header("Location:Login.php")，但问题仍然存在。这个网站以前是正常工作的，突然间当我再次运行它时，它就出现了这个错误，无法解决。
