Hi Support ,

I has checked you have mention on SKU Generator for WooCommerce plugin description “Add product searching by SKU on frontend” . So i was installed the free available version of the SKU Generator for WooCommerce plugin and also checked the checked box option for Search by SKU in the plugin setting but its not working with default wp search . Could you please let me know on which version (free or pro ) this sku serach on frontend feature available and its work with default wp search or any other ?
