Display product and page categories in grid

Hi,

I foolishly overwrote my theme’s functions.php file and had no backup. It seems I have restored most of everything back to how it originally was (I am not the original creator of the page so have no access to the themeblvd files), but I am missing one last thing. If you go to any of my woocommerce product category pages (under industrias menu), it should show a grid of subcategories with image and title. Right now it is only showing one

What I imagine is happening is I had found a way to make categories show up as post grids and now they wont. The same is happening with the Recursos menu, where it used to be a grid of the titles of pages, and now nothing is showing up. I think I am missing the original theme’s grid layout configuration or something
