My default page layout comes up as side by side. Don't want that.

I do not use anything too fancy when using LO. I haven’t used it in awhile, but was surprised to find that a document I was composing was being displayed as pages side by side. I just would like the normal single page display, but don’t know what change to make to have that happen.
Please help me.
Thanks!
