The most important step in order to have a blog is to create a blog page.
Create a New Page, and when the new page is loaded, make sure you change the title and the url from New Page & new-page to My Blog/News, etc, and the url to news/blog or anything else you want your blog to be named.
Drag the Posts element into the main area of the page. (Make sure you don’t drag the Post element into a global region, like the Header that contains the menu)
You will be asked to select if you want to have a single post or a Post List. Since we’re creating the blog page, please select “Post List” and click Continue.
Now Save the page. We’ve setup the Blog page. It’s time to write our first blog post. The blog page will automatically update with the latest blog posts you’ll publish.
