have you looked everywhere? just joking.
When you say dashboard do you mean the wp-admin?
Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.
