I recently built a WordPress site using the Yuma theme by Shark Themes. I wanted to find a way to remove the static credential in the footer: "Yuma by Shark Themes":

How to remove a function from a WordPress parent theme using functions.php
1) Use a child theme. If you make this change to the parent theme, it will probably be overwritten the next time you update the theme.
2) Add the following empty function to the functions.php file in your child theme (/wp-content/themes/yuma-child/functions.php):
