Remove Powered by Tempera & WordPress

Thanks for replying. So now here is what my functions.php looks like now. I uploaded it to my child theme, mirroring the same place in the directory as the parent theme has its functions.php

It made my site page go blank.

<?php
/*
 * Functions file
 * Calls all other required files
 * PLEASE DO NOT EDIT THIS FILE IN ANY WAY
 * Catherine to remove powered by....
 * @package tempera
 */

// variable for theme version
define ("TEMPERA_VERSION","1.0.0");

require_once(dirname(__FILE__) . "/admin/main.php"); // Load necessary admin files

//Loading include files
require_once(dirname(__FILE__) . "/includes/theme-setup.php");     // Setup and init theme
require_once(dirname(__FILE__) . "/includes/theme-styles.php");    // Register and enqeue css styles and scripts
require_once(dirname(__FILE__) . "/includes/theme-loop.php");      // Loop functions
require_once(dirname(__FILE__) . "/includes/theme-meta.php");      // Meta functions
require_once(dirname(__FILE__) . "/includes/theme-frontpage.php"); // Frontpage styling
require_once(dirname(__FILE__) . "/includes/theme-comments.php");  // Comment functions
require_once(dirname(__FILE__) . "/includes/theme-functions.php"); // Misc functions
require_once(dirname(__FILE__) . "/includes/theme-hooks.php");     // Hooks
require_once(dirname(__FILE__) . "/includes/widgets.php");     // Hooks
require_once(dirname(__FILE__) . "/includes/ajax.php");     // Hooks

function remove_some_actions () {
   remove_action( 'cryout_footer_hook' ,'tempera_site_info' ,99 );
}
add_action('after_setup_theme', 'remove_some_actions');
?>

I think that all you need in your functions.php is the following:

<?php
function remove_some_actions () {
   remove_action( 'cryout_footer_hook' ,'tempera_site_info' ,99 );
}
add_action('after_setup_theme', 'remove_some_actions');
?>

That worked! Thanks very much.
