codeigniter - Plesk 禁止 403 获取引导样式（nginx）

Question

我在主机中安装了 PLESK，并创建了一个子域“app.mysite.com”。在这个子域中，我使用以下结构上传了我的 codeigniter 项目：

当我尝试访问“css”文件夹以获取 boostrap.min.css 文件（app.mysite.com/css/bootstrap/css/bootstrap.min.css）时，我收到此禁止错误：

这是此站点的 HTTP 的附加指令：

而另一个用于 HTTPS：

该网站自动从 HTTP 重定向到 HTTPS。

最后，我将此代码添加到其他 nginx 指令中：

其他测试

我尝试更改“附加 nginx 指令”，以从 URL 中删除 index.php：

但是没有加载样式文件，codeigniter 读取 url 作为控制器调用返回“404 page not found”：

请，我需要有关此问题的帮助以及如何正确配置 nginx 以访问 css/、js/ 和 img/ 文件夹文件。谢谢

我找到 app.mysite.com 子域的 nginx.conf 文件：
