This is a test post and supposed to show full width, without a sidebar. But it doesn’t and I don’t know why.
I read through this here https://www.wpeka.com/how-to-remove-the-sidebar-in-wordpress.html
I had already set up a fullwidth page template, which kind of works for pages but I can’t assign it to posts.
Image below is set to show at maximum width. still crammed.
