Update 2.3.1 business all items disappeared

Hallo. I updated right now to business 2.3.1 form the joomla update panel.

Now when i go to the product category i only get the related modules of category put the products are disappeared !!

for example:

www.ilmondodiwit.com/shop/gioielli/26-ciondoli.html

here you see the subcategories and the related modules like related products most sold ecc.. but the products of the category are disappeared

PLEASE GIVE ADVICE Thanks for your kind reply

Thanks for your reply.

actually it depended on an sef component installed on my site which has often issues with the urls with hikashop. Always small things. I purged all urls created and now it works. It is not nice. Fortunately i get recreated the same urls (nearly) but its always a big job to do.
i'm sorry about that but i'm using hikashop and the sef component which is also anvery good component but both together it give me often issues.

Thanks again.

Regards
