I wonder if someone could help me.
I just upgrade my wordpress and start to use taxonomy.
what I want to do is to query posts from different categories.
I used to do it like this
but with taxonomy added to my categories, doesnt work anymore for example if I go to a category page the link goes like this
I guess my taxonomy category name is "ad-category" and the category name is cars
but how could I query posts from categories ids, example 5,6,7,8 etc..
Thak you for your time!!
