The unsubscribe link doesn't work in automessage

The unsubscribe link in automessage leads to a page error (page doesn't exist)

To stop receiving messages from mysite click on the following link: http://mysite.com/unsubscribe/d6f4f3aaa15e44c46eba19b68af8d4dc
How do I fix?

P.S
My wp-content folder is moved WP_CONTENT_DIR
