Side panel vanished from template

I published a post yesterday and my right panel from my freshy theme somehow vanished and ended up underneath the last blog post at the bottom of the page.

I really don’t know anything about the tech side of wordpress, it was set up for me, I really don’t even know what version it is, I’m just going by what was at the bottom of the page in the backend.

I literally publish my articles and that’s it.

If anybody could help, would really appreciate it.
