### Error Message

**Title: api\_chat.php returns 403 while another PHP file with identical content works**

Hello InfinityFree community,

My website is [quanlykhodanpianonguyenduy.gt.tc](https://quanlykhodanpianonguyenduy.gt.tc/).

My PHP chatbot works on localhost, but on InfinityFree, requests to `/api_chat.php` return HTTP 302 and redirect to `https://errors.infinityfree.net/errors/403/`, which returns 403 Forbidden.

**What I have tested:**

- Created `/kiemtra.php` in `/htdocs`. It displays “PHP hoạt động” successfully.
- Replaced the entire contents of `/api_chat.php` with the same minimal code:

```php
<?php
header('Content-Type: text/plain; charset=utf-8');
echo 'PHP hoạt động';

```

- `/api_chat.php` still returns 403 when opened directly, while `/kiemtra.php` works.
- Deleted and recreated `api_chat.php` using File Manager, but the issue remains.
- Both files are in `/htdocs`, and the filename is exactly `api_chat.php`.
- The parent `.htaccess` I checked only contains `DirectoryIndex` and `ErrorDocument` directives. I have left it unchanged.
- I could not find a way to change file permissions in File Manager.

The minimal test contains no database connection or external API calls.

Could you please help me determine whether this is caused by file permissions, a path-specific restriction, or another hosting configuration issue? What should I check next?

Thank you!

> Getting a 403 error means the server is refusing to show your webpage. Here are the most common causes and how to fix them: 1. Website Files Are in the Wrong Location The Issue: Your domain might be pointing to an empty or non-existent folder.

But to summarise, because both API’s and live chat systems can’t be hosted here (you can host it else where, and embed it here, it just cant run on InfinityFree servers) certain key words, including “Chat” automatically redirect to a 403 page.

The other thing that might cause you a problem with your project, is that the security system will block any none-browser connections going to your site. Since InfinityFree is for hosting websites not API’s
