I have had a guy helping me setup a sync plugin that get products from the POS system that we use, over to woocommerce. The issue is that after he have done some update of the DB I'm not able to add multiple products to categories, I have to do it one by one... The product do have the category connect / check if I go in to the product, it just do not show up in the category on the site. If I go in to the product and click "save" without doing anything, it then snow up in the category.
I have used the recount terms under woocommerce -> system tools -> tools but that did not help.
Any body that can help me out - will really make my day :-)
