4. Open the functions.php file and add the following code:

function replace_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', get_template_directory_uri() . '/path-to-your-jquery-file/jquery.min.js', array(), null, true);
        wp_enqueue_script('jquery');
    }
}
add_action('wp_enqueue_scripts', 'replace_jquery');
    

Replace /path-to-your-jquery-file/jquery.min.js with the actual path to your jQuery file.

Test Your Site

After updating jQuery, test your site. Check if everything is working as expected. Pay attention to interactive elements like sliders, menus, and forms.

• JavaScript Errors: Open your browser console and look for error messages. They can help you identify the problem.
• Fallback Option: If you encounter many issues, you can revert to the previous jQuery version. Simply remove the code you added in the functions.php file or deactivate the jQuery Updater plugin.
