Hi How to hide the seller’s name on the products?

Hi @atebbaa,

There are 2 ways you can do it:
1. Use the css code: Add into the custom css in Theme Options:

.by-vendor-name-link{ display: none !important; }

2. Use the code: You can custom the Main theme but we do not recommend this way

if (class_exists('WeDevs_Dokan')) {
remove_action('woocommerce_shop_loop_item_title', 'armania_dokan_sold_by_text', 6);
remove_action('woocommerce_single_product_summary', 'armania_dokan_sold_by_text', 6);
}

With any way, you should do the backup if you want to update the theme in the future
