Your theme was stored in wp-content/themes/cakifo, where cakifo was the name of your theme.
By renaming the theme directory to something like :
wp-content/themes/test_cakifo you should be able to get to the admin panel, select a new theme and get your site back. Do you have the default wordpress themes in your theme directory (ie twentyeleven, and twentyten)? You could pick one of the default themes to get the site back and running.
I'm not sure what you are doing but it looks like you uploaded a new theme? Do you know about file structures and such?
One final thought....If you are not comfortable with any of this, find someone you trust that knows wordpress to help you.
