What steps can be taken to troubleshoot issues with a config file not affecting any changes in the output of PHP scripts?

If changes made to a config file are not affecting the output of PHP scripts, the first step is to ensure that the config file is being properly included in the PHP script. Check for any typos or errors in the file path or syntax of the include statement. Additionally, verify that the changes made in the config file are correct and compatible with the PHP script. Finally, clear any cache or restart the server to ensure that the changes take effect. 

<?php
// Make sure the config file is properly included
include 'config.php';

// Verify that the changes in the config file are correct
// For example, if changing a database connection, ensure the credentials are accurate

// Clear cache or restart server to apply changes
