Hello,
1/ Theme Options > Blog > Blog layout > Sidebar Position > Apperance > Widgets > add content into Main sidebar area. Content of men mentioned sidebar will be displayed on Blog and single post pages.
As I can see, once you add more posts with the same categories, you will be able to see 3 posts per row onto the Related area.
I found the comment area on the blog post is below the related posts, like this: https://gyazo.com/9e453afcceadc58b247a72f157c2207b, is there any method to exchange these two sections?
– provide URL, please.
2/ Theme Options > Breadcrumbs > Special Breadcrumbs On Cart, Checkout, Order Page > Off
