Product does not show the "'sold by …… vendor'

Hello,

We have a lot of requests and some problem with your access caused delay, but it’s not our fault, you gave the incorrect access.
There is no problem to show the product vendor at the shop page and we even created an example on our demo
http://prntscr.com/s7y657

To show it you just need to add the following code to child theme functions.php

add_action( 'woocommerce_after_shop_loop_item_title','sold_by' );
function sold_by(){
        global $product;
        $seller = get_post_field( 'post_author', $product->get_id());
        $author  = get_user_by( 'id', $seller );
        $vendor = dokan()->vendor->get( $seller );

        $store_info = dokan_get_store_info( $author->ID );
        if ( !empty( $store_info['store_name'] ) ) { ?>
                <span class="details">
                    <?php printf( 'Sold by: <a href="%s">%s</a>', $vendor->get_shop_url(),  $vendor->get_shop_name() ); ?>
                </span>
        <?php 
    } 
}

You switched to another theme, so I can’t add it for you.

Besides this question is related to Dokan plugin more than to theme because WC Product vendors plugin display product vendor on the stop page by default as you can see at other demo where this plugin is installed https://xstore.8theme.com/demos/jewellery/shop/
But Dokan plugin doesn’t have such option and you have to do this by additional customization.
