Total not updated

Update: if i refresh the page, the price change correctly…

Hi @paolo8913

Looks like the add on plugin does not update totals via ajax. Try adding this code to your functions.php & check if it works with ajax

add_action( 'wp_footer', function(){
	?>
	<script type="text/javascript">
		jQuery(document).ready(function($){
			$( document.body ).on('added_to_cart xoo_wsc_cart_updated', function(){
				// refresh fragment on document load
				$( document.body ).trigger( 'wc_fragment_refresh' );
			})
		})
	</script>
	<?php
} );
