    PHP message: PHP Warning: Constant WP_DEBUG_DISPLAY already defined in /var/www/vhosts/bla/httpdocs/wp-config.php on line 81" while reading response header from upstream

    I have this error in the logs although I no longer have WP_DEBUG_DISPLAY in wp-config.php. Can someone explain this?

    Might you have more than one wp-config.php file? (One in the “normal” home directory, one one level above.) Or, what’s in lines 75-85 of wp-config.php?

    There was nothing special on these lines and there was no other wp-config. It was a issue with PHP FPM 8.2.17 provided by Plesk. I downgraded to 8.1. Everything is fine now.
