What are some potential issues with using JavaScript to modify scripts for user configuration on a website?

One potential issue with using JavaScript to modify scripts for user configuration on a website is that it can be easily manipulated or disabled by the user, leading to security vulnerabilities or unexpected behavior. To solve this issue, you can use server-side scripting languages like PHP to handle user configuration changes, ensuring that the logic is securely processed on the server side. 

<?php
// Check if user is logged in and has permission to modify configuration
if($user_logged_in && $user_has_permission) {
    // Process user configuration changes securely on the server side
    $new_config_value = $_POST['new_config_value'];
    // Update configuration in database or file system
}
?>
