Help! Dashboard Screen Blank!

When I log into the wp-admin portion of the my site, the dashboard options show up (Updates, Posts, Media, etc.), however the rest of the screen is blank.

The website itself is still working. But I have no ability to edit it anymore. I tried using FileZilla like recommended for the “white screen of death”, but that didn’t work either (it just kept declining my login – so I’m sure that’s a whole different issue.)

I’m trying to fix up a website by a deadline and I am truly at a loss now.

Please help!
