wp-debug fatal error

I keep receiving this issue on my site:

Your site is set to log errors to a potentially public file
Debug mode is often enabled to gather more details about an error or site failure, but may contain sensitive information which should not be available on a publicly available website.
The value, WP_DEBUG_LOG, has been added to this website’s configuration file. This means any errors on the site will be written to a file which is potentially available to all users.

is there any way to turn this off?
