Never, ever, ever edit the parent files directly. You will lose your changes when the parent files are updated and that is almost certainly going to happen.
Instead create and activate a child theme called “Verbo Child”.
https://codex.www.ads-software.com/Child_Themes
– Make a directory called wp-content/themes/verbo-child
and put these 2 files in it.
verbo-child/style.css
Which contains
/*
Theme Name: Verbo Child
Description: Verbo Child Theme
Template: verbo
Version: 1.0.0
*/
Then make verbo-child/functions.php
and put these lines in it.
<?php
add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style' );
function enqueue_parent_theme_style() {
wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
Now copy the file verbo/footer.php
into verbo-child/footer.php
and edit that in your favorite text file editor.
Locate line number 43 in the copy and change it from
<p><?php echo 'Copyright © ' . date( 'Y' ) . '. Powered by <a href="https://www.ads-software.com" target="_blank">WordPress</a>.'; ?></p>
to
<p><?php echo 'Copyright © ' . date( 'Y' ) . '. Powered by <a href="https://www.ads-software.com" target="_blank">WordPress</a>.'; ?></p>
Or whatever you like. Raw HTML will work too.
By doing it this way, when the theme is updated then you will not lose your edits. Ideally the footer would have some sort of filter to modify that (it may, I spent only 15 minutes looking at this) but this will work too.
