Sidebar outside of content.

Hey,

Not sure what's happened, but Sidebar is being called outside of the content div, making it display below the content, rather than next to it.

Its not a new change, so i dont understand why its only just started to mess up the site.

I've changed it in the child theme, now it works, but is that a glitch, or am I just being stupid?
