 * Since 2.8.16, we’re seeing…
 * `PHP Warning: Undefined array key "dhl_tracking_url_language" in /srv/wp-content/
   plugins/dhl-for-woocommerce/includes/class-pr-dhl-wc-order-paket.php on line 
   489`
 * … repeated dozens of times (far more than we place orders) in the logs.
 * So far no reports of negative effects.
 * PHP 8.0.20
    WP 6.0 WC 6.6.1 DHL 2.8.16

 * [@isarisar](https://wordpress.org/support/users/isarisar/) hi!
 * Does this appear in the log file right after you create a label?
    What can be
   the trigger for this error?
 * Best,

 * Hi, sorry for the delay. I haven’t seen the warning since I clicked update on
   the plugin’s settings page, and so also can’t try & find anymore how it occurred.
 * Maybe the setting isn’t being written into the db during the update?

 * [@isarisar](https://wordpress.org/support/users/isarisar/) if the plugin works
   fine and there are no issues then it might be some warning that does not affect
   the functionality.
    Happy to hear that everything works for you!
 * Best,
    Ilya
