Cart doesn't disappear when switched to catalogue mode

Hi!
Sorry for the delay, try to put this code in your “functions.php” file and let me know.

add_action('wp_footer','hide_cart_widget');
function hide_cart_widget(){

	if ( get_option( 'ywctm_hide_cart_header' ) == 'yes' ) :

	?>
		<style type="text/css">
			<YOUR_CART_CSS_CLASS_OR_ID>{
				display: none !important;
			}
		</style>

	<?php

	endif;

}
