Hi.
First, congratulations on your extension; It Is very useful.
The problem is that I can't sort the products on the front-end in alphabetically order.
I think I have configured everything correctly, but I can't get it.
As you can see in the images, in my opinion everything is configured to be displayed in alphabetical order, both in the Hikashop configuration, and in the menu items. I have even tried to modify the show.php without success.
Thanks for your help.
My version is HikaShop Business: 4.3.0

Hello again.
Sorry. I Forgot to telling you that the products show in alphabetical order. The issue is with the "next product" and "previous product" arrows inside the products page.

Hi,

The next / previous buttons on the product details page are based on the ordering of the products in the main category of the product, not the ordering you configure in the menu item.
So what you describe is "normal".
Now it could be improved in the future but for now the only solution is to properly enter the order of the products in each category in your backend products listing.
