It doesn't look like your scheduled tasks are running. Try running them manually and see if it updates the Next Time column to be sometime in the future. And then make sure you see them actually running. You may want to truncate your session table via phpMyAdmin.

edit: I guess you got your site back. But, looking at the source code, it doesn't look like you are using a default footer template and so the cron job image isn't in there and thus the Scheduled Task is not running. You also have two sets of </body> and </html> tags, which is not proper html. And, you are missing the vBulletin copyright, if you haven't paid for branding free.
