# Troubleshooting & Frequently Asked Questions

Common issues you might encounter while using Multi-PHP and how to fix them.

---

## 🚫 Service Fails to Start

This is often caused by **port conflicts** with other software.

- **Nginx & Apache (Port 80/443)**: Check if Skype, IIS, or another XAMPP/WAMP environment is running and using Port 80.
- **MariaDB (Port 3306)**: Check if you have an existing MySQL or MariaDB installation running.
- **Solution**: Go to `Settings > General` and change the conflicting port to something else (e.g., Change Nginx to 8080 or MariaDB to 3307).

## ❌ PHP Error: "No input file specified"

This usually means Nginx or Apache cannot find your project's PHP files.

- **Verify Project Path**: Check if the project path in "My Projects" is correct.
- **Trailing Slash**: Ensure your project path doesn't end with an extra trailing slash unless necessary.
- **Restart Services**: Try stopping all services and starting them again.

## 🔒 403 Forbidden Access

Permissions or configuration issues can block access to your local site.

- **Index File Missing**: Ensure your project folder contains an `index.php` or `index.html`.
- **Nginx Config**: If using Nginx, check the project-specific configuration for any manual `deny` rules.
- **Directory Indexing**: By default, Multi-PHP allows directory indexing. If it's blocked, you must have an index file.

## 💻 CLI Commands (php, mysql) Not Working

- **PATH Not Updated**: You must click "Sync Commands" in the CLI settings.
- **Terminal Window**: Close and reopen your terminal (CMD, PowerShell) for the changes to take effect.
- **Check Integration**: Ensure the "System PATH Integration" toggle is ON.

> If you're still having trouble, check the **"Service Logs"** for detailed error messages from the PHP, Nginx, or MariaDB binaries.
