I have finished my site and thought I should back it up. What a disaster the site is now completely blank and I cant access the admin area either http://www.cellar2door.com
I know that there are lots of similar posts and the answers all seem to point to changing the php to 664.
However, I am a real noobie and have no idea where I do this. Can someone point me in the right direction so i can try and fix it.
