Apache 2 302 执行 php 脚本时出错

Question

这个程序已有 4 年历史，但我正在努力让它发挥作用。 https://github.com/msaad1999/KLiK-SocialMediaWebsite 我按照所有说明进行操作，一切似乎都正常，但在单击登录按钮后，我在 Apache 2 中收到以下错误。我也确实在两个文件夹中添加了一个 .htacces 文件。

::1 - - [21/Apr/2023:15:55:30 -0500] "POST /socialmedia/includes/login.inc.php HTTP/1.1" 302 354 "https://sourcecodedepot.com/socialmedia/ login.php" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Edg/114.0.0.0"

在研究 302 是某种不起作用的重定向之后，标头确实显示 login=success 但它没有重定向。如果您查看注释掉的代码，我试图将其重定向到我的主页，但没有成功。我是 php 和 html 的新手 1 有 2 个问题 1 我不确定 ../ 是什么意思 我假设它进入下一个文件夹？ 2 我怎样才能让重定向回到默认页面不知道默认页面应该是什么。这是错误日志中引用的代码

<?php
