Debug error on my website

I have a critical error on my wordpress website, its a debug error and says this
‘Your site is set to display errors to site visitors
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_DISPLAY, has either been enabled by WP_DEBUG or added to your configuration file. This will make errors display on the front end of your site.
