登录后页面无法正确重定向。页面无法正确重定向

Question

我已经在我的网站上创建了一个登录页面。这应该将用户重定向到index.php并隐藏登录和注册页面。但这就是我得到的；

“页面无法正确重定向

Firefox已检测到服务器正在以永远无法完成的方式重定向对此地址的请求。

This problem can sometimes be caused by disabling or refusing to accept cookies."

但是我没有在页面上设置任何cookie。

登录脚本如下：

<?php
if(isset($_POST['login-submit'])){
    include 'dbh.inc.php';
    $mailuid = $_POST['mailuid'];
    $password = $_POST['login-password'];

    if(empty($mailuid)){
        header("Location: ../login.php?error=emptymailuid");
        exit();
    }
    if(empty($password)){
        header("Location: ../login.php?error=pwdempty");
        exit();
    } 

  $sql = "SELECT * FROM users WHERE usersEmail=? OR usersUsername=?";
  $stmt = mysqli_stmt_init($conn);
  if(!mysqli_stmt_prepare($stmt,$sql)){
      header("Location: ../login.php?error=sqlError");
      exit();
  }else{
      mysqli_stmt_bind_param($stmt,"ss",$mailuid,$mailuid);
      mysqli_stmt_execute($stmt);
      $result = mysqli_stmt_get_result($stmt);
      $resultCheck = mysqli_num_rows($result);
      if($resultCheck > 0){
         if($row = mysqli_fetch_assoc($result)){
            $isActive = $row['usersActive']; 
           if($isActive == "Yes"){
               $passwordCheck = password_verify($password,$row['usersPassword']);
             if($passwordCheck == false){
                 header("Location: ../login.php?error=wrongpwd");
                 exit();
             }else if($passwordCheck == true){
                 session_start();
                 $_SESSION['id'] = $row['usersID'];
                 $_SESSION['userId'] = $row['usersUsername'];
                 $_SESSION['email'] = $row['usersEmail'];
                 header("Location: ../index.php");
                 exit();
             }  
           }else{
               header("Location: ../login.php?error=notActive");
           }
         } 
      }else{
          header("Location: ../login.php?error=noUser");
          exit();
      }
  } 
}else{
    header("Location: ../login.php");
    exit();
}
