When somebody confirms via the link in the subsrciotion mail, the page that opens ist showed correctly, but there ist that “notice”:
Notice: Undefined index: confirmed_tracking in /var/www/web1202/html/wp/wp-content/plugins/newsletter/includes/controls.php on line 356
I already stopped the debug-mode in the wp-config.php.
What can I do?
beside this everything is working fine!
Thank you for help!!
