Custom Widget Area #1 not visible in footer after upgrade

After upgrading from Sydney to Sydney Pro, the Custom Widget Area #1 content has disappeared from my footer, despite making no changes to it. When I switch back to the free theme, it appears again. The footer widget area settings and the code are the same in both (code appears below):

<?php dynamic_sidebar('smartslider_area_1'); ?>

How do I get this to display properly in my Child Theme?

Hello there,

Sydney doesn’t have smartslider_area_1 sidebar ID in its core code. Did you add it to theme’s files? You should use a child theme’s functions.php file to define a new sidebar location. And copy the footer.php file from main theme’s folder to child theme’s folder. And put <?php dynamic_sidebar('smartslider_area_1'); ?> in there.

Before doing all of there, you have to transfer your settings have done in free version to Sydney pro by following this simple tutorial:

Thanks for your response. Yes, I added the SmartSlider plugin because I needed a responsive slider for the hero area. It’s placed via a shortcode.

I will follow the steps you outlined but I may have some follow up questions. I am not fluent in php.
