In our theme we use Posts for deals and directory items. But it’s common need when you want to have separate Blog Posts section. To do this, go to Theme option Affiliate Enable separate blog post type
You can also change permalinks of categories, blog, etc. Don’t forget to resave permalinks after changes Settings Permalinks .
If you need to show separate section on your home page for Blog posts – use Page builder. Each post module of page builder has next option
If you want to show posts only from one category – place “blog_category” in Taxonomy slug and write slug of your category which you want to show. You can fill slug in Blog Posts Blog category Edit .
