I have linked the posts transferred from the live website to this development website to Article page through Reading. I want to show all posts so I linked the Post pages to Article page as you can see here. However, since there are many posts that were published in the past, I would like to have an archive on the sidebar. How do I set it on? On the edit Article page, I set the Page Attributes to Layout Content Left, Sidebar right. And in the Widget, I set Archives on the widget and set Manage Sidebars. However, I fail to see any sidebar on the Article page.
