Hi,
Please open to edit up-sells.php file at /joyn/woocommerce/single-product/
Find this code:-
$upsells = $product->get_upsells();
if ( sizeof( $upsells ) == 0 ) return;
$meta_query = $woocommerce->query->get_meta_query();
$args = array(
'post_type' => 'product',
'ignore_sticky_posts' => 1,
'no_found_rows' => 1,
'posts_per_page' => $posts_per_page,
'orderby' => $orderby,
'post__in' => $upsells,
'post__not_in' => array( $product->id ),
'meta_query' => $meta_query
);
Change to :-
$args = array(
'post_type' => 'product',
'ignore_sticky_posts' => 1,
'no_found_rows' => 1,
'posts_per_page' => 5,
'orderby' => 'rand'
);
Thanks
Mohammad
