Can You Manually Add Code To A Page To Display Blog Content?

Hello I have a quick question that is causing me a lot of trouble with the default blog location on WP. I would like to have the blog display on a page titled “blog”, I know how original huh. The problem is that when I switch this in the Settings >> Reading area of the admin panel, it does not display the blog items correctly or at all actually, when the page is clicked from the top menu, I just get a blank page. In fact if I change the home page to a page, I then get a list of pages not blog posts. I don’t know if this is caused by a plugin I have installed or possibly the theme being used.

So, my question is this. Is it possible to simply add a short code or something similar to a blank page to have it list the blog content block manually?

Thanks in advance for your help,
