Well, you can choose to simply ignore it. Developers include these so that the plugin or theme can be updated automatically or so that you can register for support. All the items on GPLVilla will work perfectly fine without anything being entered in the license key box.

We would recommend updating your theme/plugins manually when updates become available on our site.

Hide License Notification Nag

With that being said, Sometimes those notices stick on top of the WordPress dashboard and can’t be closed. In that case, You can use this code snippet in your child theme’s function.php file

add_action('admin_head', 'my_custom_notification');
function my_custom_notification() {
	echo '<style> 
	.update-nag, div#message.notice,.notice-error, .notice-warning, .error, .yith-license-notice {
		display: none;
	}
	</style>';
}

Using Plugin to Hide Notices individually

If you don’t want to use the code snippet to hide the annoying license activation notices or would like to hide notices individually. Disable admin notices plugin is the perfect choice in that case. It’s a free and very popular plugin in the WordPress repository with more than 80,000 active installations.
