password-auto-generator Common Issues

## Common Issues

### 1. 404 Not Found for `/` or `/generate`
- **Cause:** The `index.html` file is not in the correct folder, or the folder is not named `templates`.
- **Solution:**
- Ensure your folder is named `templates` (all lowercase).
- Place `index.html` inside the `templates` folder.

### 2. Flask Not Installed
- **Cause:** Flask is not installed in your Python environment.
- **Solution:**
- Run `pip install flask` in your terminal.

### 3. Port Already in Use
- **Cause:** Another process is using port 5000.
- **Solution:**
- Stop the other process, or run Flask on a different port:
`app.run(debug=True, port=5001)`

### 4. Password Not Generating or API Not Working
- **Cause:** JavaScript fetch to `/generate` fails, or backend is not running.
- **Solution:**
- Make sure you started the Flask server with `python password.py`.
- Check browser console for errors.

### 5. Changes Not Reflected
- **Cause:** Browser cache or server not restarted.
- **Solution:**
- Hard refresh your browser (Ctrl+F5).
- Restart the Flask server after code changes.
