Help, help, help!!

'Ello gov'na! lol :)

I need some assistance from all my smart bloggy friends. I am unable to change the background on my blog and as you can see, it's back to the plain beige again now. I have tried all sorts of different background codes and actual sites as well. I've also tried in Internet Explorer, Google Chrome, and Firefox. Lastly, I tried on my friend, Cat's, computer in case it was my computer specifically. So far it's none of those things!!!!


Can someone help me please!?
Thanks SO much,
Hannah
