Reply To: Show all categories on product category page

Hello,

I am checking the shop widget area in Appearance > Widgets: https://gyazo.com/4dd51124ce00fd35a4a86a9d6247e2f3

You see you have added the Attribute filter. It means that if there are no products assigned to this filter, it will not appear. This is the way Woocommerce works and our WoodMart filter is based on the main functionality.

You need to add the Product categories widget to the Shop page widget area.

If you have any questions please feel free to contact us.

Best Regards
