Blog post view after continue reading is clicked

Upon clicking continue reading, when the blog post opens fully, the way the post looks is different now post upgrade. Previously, the blog post would open and the remaining modules that I had set for the site on the sides would stay. Now, the blog post opens full screen, which makes the post format in such a way that I do not like.

Is there a setting I that I am missing to force the blog post to display previously?
