Question

最近我一直在尝试设置我的第一个登录页面，并且在我的本地主机（XAMPP）上正确设置但是当我将所有内容上传到我的 cpanel（包括将数据库设置到 phpmyadmin）时，每当我去我的索引（.php）并单击我的登录页面（login.php）它会在空白页面上返回此错误：“无法连接！”这是我的“login.php”文件的内容，如果有帮助的话。任何帮助表示赞赏！ |编辑：错误发生在我的网站“https://nexium.cc”上，我使用的是 namecheap 托管 :)
错误发生在此页面上：来自主页的“https://nexium.cc/login.php”：“https://nexium.cc/index.php”

<?php 

session_start();

    if($_SERVER['REQUEST_METHOD'] == "POST")
    {
        //something was posted
        $user_name = $_POST['user_name'];
        $password = $_POST['password'];

        if(!empty($user_name) && !empty($password) && !is_numeric($user_name))
        {

            //read from database
            $query = "select * from users where user_name = '$user_name' limit 1";
            $result = mysqli_query($con, $query);

            if($result)
            {
                if($result && mysqli_num_rows($result) > 0)
                {

                    $user_data = mysqli_fetch_assoc($result);
