Blank WP-Admin Page

Hey all,

I’m pretty new to the WordPress development scene but I’m attempting to set up my own blog on my website http://www.plusbits.co.uk/words/

Everything installed fine a month or so ago and I’ve been developing my theme ever since, but for some reason last night I was greeted with nothing but a blank page when trying to log into WP-Admin. I re-installed everything from scratch and it seemed to fix it, only I’m encountering the same problem yet again today. I don’t know why it’s happening at all, whether it’s something in my theme (which I doubt) or a plugin (which again, I doubt since I don’t have any installed aside from those that came with the install!).

Any ideas would be extremely useful as I’m close to tearing my hair out!
