Dashboard width problem

Hi.

I was hoping someone would be able to help me with this:

Normally the dashboard spans across the entire page width like so:

However, in this dashboard, there’s white space to the very left:

Whereas it’d normally fit to the entire width (which it was doing until I signed in this morning).

I find it a tad annoying, is there any way to fix this?
Thanks in advance.
