WP Adverts doesnt show up Post by Category

Hi Ive been using WP adverts for a while now and worked fine but i reccently noticed a big problem that affects the navigation of my posts.

I have a page with a grid of all my categories displayes along with a search bar, but once i click on one of the categories, the page that is suppossed to show all the categories shows nothing at all and it happens with all the categories, can you help me to solve this?

Thanks in advance
