Thanks for your reply. I'm just starting to learn php so the I'm having a hard time with the syntax.
When I do this I get an syntax error after the the word else :
if ( get_theme_mod( 'copyright_textbox' ) ) :
echo get_theme_mod( 'copyright_textbox' );
else :
<div class="site-info">
"><?php printf( __( 'Proudly powered by %s', 'AC' ), 'WordPress' ); ?>
<span class="sep"> | </span>
<?php printf( __( 'Theme: %1$s by %2$s.', 'AC' ), 'Artistic Collaboration', 'Underscores.me' ); ?>
</div><!-- .site-info -->
endif;
?>
