I'm feeling a bit blonde here...
I have WP 3.2.1 and have created my own site a couple of months ago. I would now like to create another site in addition to my existing site (will be a separate domain), but don't have multisite.
Firstly, I don't understand how to back-up my files/database...?
Secondly, I'm not having much luck upgrading(?) to multisite and things like "codex" etc don't mean a lot to me...being as "blonde" as I am ;-)
Is anyone able to explain this to me in a way that I will understand? Is there a simple way to do any of this?
