rocksandbubbles on "Remove credits in theme sixteen"

I managed to create a childtheme for sixteen. But I can't seem to be able to remove the credits 'sixteen theme by inkhive' in the footer.

this is what the footer.php contains

<?php
/**
* The template for displaying the footer.
*
* Contains the closing of the #content div and all content after
*
* @package Sixteen
*/
?>

</div><!-- #content -->

<footer id="colophon" class="site-footer" role="contentinfo">

<div class="container">
<?php if ( of_get_option('credit1', true) == 0 ) { ?>
<div class="site-info">
<?php do_action( 'sixteen_credits' ); ?>
<?php printf( __( 'Sixteen Theme by %1$s', 'sixteen' ), 'InkHive' ); ?>
</div><!-- .site-info -->
<?php } //endif ?>
<div id="footertext">
<?php
if ( (function_exists( 'of_get_option' ) && (of_get_option('footertext2', true) != 1) ) ) {
echo of_get_option('footertext2', true); } ?>
</div>

</div><!--.container-->
</footer><!-- #colophon -->
</div><!-- #page -->

<?php wp_footer(); ?>
</body>
</html>

Can someone help me?
