Where should these constants go?
These constants must always be added to your wp-config.php before the /* That's all, stop editing! Happy publishing. */ line. In PHP, a constant cannot be redefined once it has been set; WordPress core also defines its own default values for some of these constants further down, while loading its core files. If you don't define the constant first, the core's default takes effect and your define() line — even if it's technically present in the file — silently does nothing.
Setting WP_DEBUG_DISPLAY to false and WP_DEBUG_LOG to true is the recommended debugging setup for production sites: errors get written to wp-content/debug.log instead of appearing on the public page. Leaving WP_DEBUG_DISPLAY on for a live site — showing PHP errors, warnings and server file paths to visitors — is a common and well-known information-disclosure mistake, since it can leak server configuration, plugin versions and directory structure to attackers.
DISALLOW_FILE_EDIT completely disables the built-in Theme Editor and Plugin Editor screens in wp-admin. This is one of the well-known first-response steps applied after a site has been compromised, but it's just as commonly recommended as a standard hardening step from the start — because those file editors are one of the most common ways an attacker who already has admin access adds malicious PHP code directly to a theme or plugin file.
