PHP Error “Cookie names must not be empty”

Thanks for your comment! We take note of these warnings, but they are not an indication of a problem with our code. We do try to minimize these, but we also have to maintain compatibility with many different versions of PHP.

Warnings should never appear on a production webserver, and you should turn off warnings in PHP. For how to turn off php warnings, see this article: https://www.wpbeginner.com/wp-tutorials/how-to-turn-off-php-errors-in-wordpress/

If you are on a shared server and your efforts cannot make the PHP warnings go away, contact your webhost as PHP is misconfigured. Warnings should never be shown on a public webserver. If you are a developer, simply ignore these errors.
