I will give you one example to explain better my issue. I have one main category: SILVER and inside this category I have RINGS,PENDANTS e.t.c. Inside of RINGS category I have another one subcategory PLAIN SILVER. So the hierarchy is SILVER-RINGS-PLAIN SILVER. When I am looking in single page one product the related products don’t belong to this category PLAIN SILVER-RINGS-SILVER but are products from different categories. How can I solve this problem? My theme is LEGENDA and in theme options also has one choice to make enable or not the related products.
