Two products in a category are visble as you can see here: www.vetechcad.nl/luchttechniek/toebehore...chroef-pit-draaibaar

When I click on an product, it says product not found.

What to do?

Hi,

I don't see such error. Both links works fine on my end.
Could you double check ?

Sorry Nicolas, my client has decided to setup a whole new website with Hikashop.
The problem does not occur now.
