Hello Hasan-- Just installed and configured the Premium version. Great added functions. 🙂
I set up "Categories" in the Navigations screen (Terms relation: IN; Taxonomy relation: OR), and the proper categories show up on my grid. I'm having a couple of issues, though.
1. When I click on the first Category filter, it works fine--but, after the grid initially loads the expected 3 columns, it then reloads with all items in one column.
2. When I click on a new Category filter I get no results. I have to reload the blog page to get the grid to load again.
