 Hello @feminatzi - Welcome to WordPress Trac!

 In PHP, an unquoted string like the ones you have in the ticket
 description are interpreted as PHP constants
 (https://www.php.net/manual/en/language.constants.syntax.php).

 If the constants are not prior declared, you will indeed see errors.

 In a healthy site, these two constants would be declared before any user
 code is executed, so no errors are shown. The unquoted code in fact is the
 correct one; I think you have a theme or a plugin that races this
 declaration.
