I logged onto my site at http://www.doncobb.com and it tells me "ERROR: The themes directory is either empty or doesn’t exist. Please check your installation." I've tried deleting (through FTP) my existing theme folders and then reinstalling the themes I use and everyone is a failed install. I tried installing WP's twentytwelve theme and a couple other WP themes, they fail too. My page is a white blank page now! Hello! Can anyone help me with this? Thank you!
