Hello,
I have changed the number of products in search form http://prntscr.com/f6xdcb
(xstore/framework/theme-functions.php, etheme_ajax_search_action function, line 1004, ‘posts_per_page’ => 9 ) but you will need to change it again after theme update. I did not copy this function into child theme because if we make any changes or improvements you won’t get them, so it will be easy to change the number of posts for you.
Provide me correct admin panel access to check the SKU problem and fix it, because existing credentials are incorrect.
Regards
