Use of undefined constant ABSPATH

  • I started noticing errors in web server error log:

    [29-Oct-2021 20:55:10 Europe/Moscow] PHP Warning:  Use of undefined constant ABSPATH - assumed 'ABSPATH' (this will throw an Error in a future version of PHP) in /var/www/my-wordpress/wp-admin/includes/c

    Not sure what causes them, I have a semi-clean WP installation. I also noticed few mentions of the same error messages on the web but without any solution.

    Have you edited your wp-config.php file? That should be among the last lines:

    /* That's all, stop editing! Happy publishing. */

/** Absolute path to the WordPress directory. */
if ( ! defined( 'ABSPATH' ) ) {
        define( 'ABSPATH', dirname( __FILE__ ) . '/' );
}

/** Sets up WordPress vars and included files. */
require_once( ABSPATH . 'wp-settings.php' );

    $ grep ABSPATH wp-config.php
 * * ABSPATH
if ( !defined('ABSPATH') )
        define('ABSPATH', dirname(__FILE__) . '/');
require_once(ABSPATH . 'wp-settings.php');

    I can’t tell from that if that part is commented out. Please post that part of wp-config.php, from the stop editing line on down.

    It’s not commented out.

    I guess this error appears when bots are trying to access class-wp-privacy-data-export-requests-list-table.php directly.

    Update: my guess was wrong, nothing happens when file is accessed directly because the code is inside class.

    This is a part of wp-config.php from “stop editing” line:

    /* Это всё, дальше не редактируем. Успехов! */
/** Абсолютный путь к директории WordPress. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');
/** Инициализирует переменные WordPress и подключает файлы. */
require_once(ABSPATH . 'wp-settings.php');
define( 'FS_METHOD', 'direct' );

    Move the fsmethod line above the “stop editing” line.

    and?

    Do you believe that would change anything? I don’t. But I’ll watch for errors in logs. They are rare, happens only once in a few days.

    It would be great if you could trace it to a particular GET statement in the webserver logs.

    That’s a good idea. I was able to trace it. And the error still reproduces if I try to access the same URI.

    ARe you getting it directly or through a link in wp-admin? If I do

    wget https://example.com/wp-admin/includes/class-wp-privacy-data-export-requests-list-table.php

    I get an error. That file is not meant to be hit directly from a browser.

    Directly. It’s not me getting it. It’s some bots, obviously. Check User-Agent string.

    OK, then, ignore it. ??

    Thread Starter shadowlmd

    (@shadowlmd)

    And it doesn’t really matter whether it’s meant to be hit directly or not because bots don’t care. I believe, some checks must be done to avoid such issues. Like it’s done in most other places:

    // Exit if accessed directly.
defined( 'ABSPATH' ) || exit;
