“Static pages” don’t have the same sidebar look

My “pages” don’t have the same sidebar divider as my regular posts do. Could somone have a look here and tell me what I need to do?

Here is a sample page that doesn’t have the same deal for the sidebar:

https://webhobbit.net/?page_id=54

I’d like my “pages” to either look like this:

https://webhobbit.net/?p=52

or like the main page..but I don’t want the side info/links without the divider bar thing.
