Hi -@albert petersen
1.First of all you need to Create child theme
2. After that you will find footer.php file in main theme’s folder.
3. Copy and paste footer.php file in child theme’s directory.
4. Now copy and paste following code in footer.php file in child theme’s footer.php.
<?php
/**
* The template for displaying the footer.
*
* Contains the closing of the id=main div and all content after
*
* @package Superhero
* @since Superhero 1.0
*/
?>
</div><!-- #main .site-main -->
<div id="colophon-wrap">
<footer id="colophon" class="site-footer" role="contentinfo">
<div class="site-info">
<!-- The text is removed you can add any text here if you want -->
</div><!-- .site-info -->
</footer><!-- #colophon .site-footer -->
</div><!-- #colophon-wrap -->
</div><!-- #page .hfeed .site -->
<?php wp_footer(); ?>
</body>
</html>
5.Now activate your child theme and you are done.
6. Report if any problem.
Thank You!!
