Can't Find Solution To White Screen Of Death

A few days ago my client contacted me to let me know that her site was displaying a Canadian pharmacy selling viagra and such. After some research I found out about the Pharma hack. I’m a designer and don’t have much experience in development. I looked through the code and didn’t see anything that jumped out. I did a backup of the site from before the hack and it seemed to be back to normal. I then tried to put up some security measures to make sure whatever happened didn’t happen again.

Two days later I noticed the “White Screen Of Death” which has effected both the site and my ability to login. I’ve gone into myphpadmin and deleted the plugins and changed the theme in _options. Neither has done the trick. Is there anything else I can try? Some of the things I’ve read seem outside my skill level so I don’t know which direction to turn.

The site is drcorinnamurray.com. For the time being I have the site redirecting to my clients old site.
