我在 Linux共享主机服务器上的以下URL（test link）上设置了付款网关代码：
我突然开始在此链接上收到 HTTP 403 错误，甚至没有更改任何一行代码。
有趣的是，如果我从网址中删除了redirecturl=http%3A%2F%2Fmanage.india.resellerclub.com%2Fservlet%2FTestCustomPaymentAuthCompletedServlet参数，错误就会停止，但这会破坏我的付款网关完成付款的URL重定向要求。
此代码接受Razorpay的付款，并将用户重定向到我的ResellerClub帐户。
这是我的代码：
<?php
// if (session_status !== PHP_SESSION_ACTIVE) {
session_start();
// }
require("functions.php"); //file which has required functions
?>

我已经尝试了所有我知道的东西，但是这个错误似乎并没有解决。谁能帮我吗？
