    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?

    How to fix Plugin Warning

    Contact the vendor of this “Premium WP Plugin”. They built and sold the plugin, and should be in the best position to fix issues with their own licensing, especially issues related to licensing.

    Commercial products are not supported here.

    Good luck!

    Please contact the developer of the plugin. This is not a core WordPress issue.

    By the way, It’s not another plugin causing this warning. I’ve conducted a plugin conflict exam an this warning occurs even when all plugins have been deactivated. Can you help?

    Follow these steps to fix plugin errors in WordPress.
    Prepare your WordPress site for the troubleshooting:
    You should always make a backup of your site before performing any troubleshooting.
    Disable all WordPress plugins; especially any caching plugins.
    Disable WP_CACHE if your site uses it.
