Removing Creditline (D5 Simplify)

I’ve searched all over trying to remove “D5 Simplify Theme | Powered by WordPress” in the footer of their Simplify Theme, but no luck. I assumed it’d be similar to other D5 coding, but after deleting multiple different sections I keep getting the same error message.

Can anybody help tell me exactly which part of the functions.php I need to delete? Here’s the section that I believe needs editing:

// function tied to the excerpt_more filter hook.
function simplify_excerpt_length( $Length ) {
global $simplifyExcerptLength;
if ($simplifyExcerptLength) {
return $simplifyExcerptLength;
} else {
return 50; //default value
} }
add_filter( ‘excerpt_length’, ‘simplify_excerpt_length’, 999 );

function simplify_excerpt_more($more) {
global $post;
return ‘ID) . ‘” class=”read-more”>Read More…‘;
}
add_filter(‘excerpt_more’, ‘simplify_excerpt_more’);

// Content Type Showing
function simplify_content() { the_content(‘<span class=”read-more”>Read More…</span>’); }
function simplify_creditline() { echo ‘<span class=”credit”>| Simplify Theme by: <img src=”‘ . get_template_directory_uri() . ‘/images/d5logofooter.png” /> D5 Creation | Powered by: WordPress</span>’; }

Thank you so much!!! This has been a nightmare for me ??
