Blog created from "posts"

I have three posts and all are showing perfectly on my home page. Problem is that when you click on one of the photos to go to the post, you get only that post and have to click on the title of the previous post to get to it. How do I get these to be more like an ongoing blog, with multiple posts on a page? Do I need to create a separate page? And why do my sidebars not show up on all posts, but only when I sort by category or author?

Hello there,

Please share your site URL here so I check the exact situation you’re having, so I can suggest you the correct solution then.
