related products is not incremented

Hello there, i am not sure what code you used and where you added it but try this one:

function v_woo_related_slider() { 
  if (is_product()) {?>
	<script>
        jQuery('#woorelatedproducts').trigger('destroy.owl.carousel');
	jQuery(document).ready(function($) {
  	var owl = $("#woorelatedproducts");
	  owl.owlCarousel({
	      items : 4,
	      itemsDesktop : [800,3],
	      itemsDesktopSmall : [900,3],
	      itemsTablet: [600,2],
	      autoPlay: 3500,
	      itemsMobile : false,
	  });
	  });
	</script> <?php 
	}
}
add_action( 'wp_footer', 'v_woo_related_slider', 90 );

Should work
