Hi, I hope you all are doing well. After I installed a wordpress plugin i got this warning that I can’t get rid of:
Warning: Undefined array key “license_key” in /home/honestypays1/my-domain.com/wp-content/plugins/premium-wp-plugin/app/Services/PluginManager/LicenseManager.php on line 414
Warning: Cannot modify header information – headers already sent by (output started at /home/honestypays1/my-domain/wp-content/plugins/premium-plugin/app/Services/PluginManager/LicenseManager.php:414) in /home/honestypays1/my-domain.com/wp-includes/functions.php on line 6878
Is anyone familiar with this specific warning, what it means, and how to fix it?
