Products per brand not visible

[Simplisso]

Hi,

 

could anyone please help me with the following:

 

I have created a shop, where you should be able to view products per brand.

It all went fine, untill suddenly, the brand pages did not work anymore.

 

Example: this brand (Elements Optimal) has 5 products in the shop.

 

The page says "Showing 1 of 5", but it isn't actually showing the products.

Please advize.

 

Best regards
