Hi,
When I switch from category pages to the brand page, the link system works smoothly and I can go to the brand page and see the products of the brand on this page. For example;
2- However, when I try to switch from the product page to the brand, the product page is blank. It is as if no product has been entered from this brand. Sample product page is here (pic-2): https://bergatobak.se/product/marabou-daim-100gr/
Click on the brand logo on the top right of the page, on the page you go, it shows no product from this brand.
Please insert the site admin access into the Private content below the message area. We will take a closer look at the case.
Please, confirm the permission for plugins deactivation, and switching to the parent theme. As soon as we complete the testing we will enable all back, however, the site would be without plugins for 15-20 min. You would better make the full backup of your site.
