Question

当我尝试运行我的代码以通过我的远程托管数据库上的POST方法注册用户时，我在我的应用程序中混合了2个错误。第一个是：

排球服务器错误

第二个是一个非常长的混乱，基本上总结为：

此网站需要使用javascript才能运行。请在您的浏览器中启用javascript。

我很困惑，因为据我所知，我的代码中没有使用javascript。如果有人能帮我解决这个问题，我将永远感激不尽。

register.php

<?php
require_once 'include/constants.php';
$con = mysqli_connect($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);

$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];

$stmt = mysqli_prepare($con, "INSERT INTO users (name, email, password) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $username, $email, md5($password));
$stmt->execute();

$stmt->close();

和我的
