What steps can be taken to troubleshoot and resolve issues related to PHP file inclusion and HTML rendering on a website?

Issue: When including PHP files in your website, it is important to ensure that the file paths are correct and that the files are properly formatted. Additionally, when rendering HTML on a website, make sure that the HTML code is valid and properly structured. Fix: To troubleshoot PHP file inclusion issues, check the file paths and make sure they are correct. Use the `require_once` function to include the PHP files to avoid including the same file multiple times. 

<?php
require_once('path/to/file.php');
?>
```

To troubleshoot HTML rendering issues, validate your HTML code using an online validator tool to ensure it is properly structured. Make sure all tags are properly closed and nested. 

```html
<!DOCTYPE html>
<html>
<head>
    <title>My Website</title>
</head>
<body>
    <h1>Hello, World!</h1>
</body>
</html>
