Hello @gorskit74,

Thanks for asking.

You are seeing a PHP warning message. You can get rid of this message by turning off the debug mode. You can do this by opening wp-config.php and adding/changing:

define('WP_DEBUG', false);

When you revisit the page, you should no longer be seeing the message.

Please let us know how it goes.

Thanks.

Hi There,

We do not recommend to use PHP 7.2.x as it has been released very recently so some functionalities aren’t applicable, depreciated or it will introduce new conflicts.

We do recommend to use PHP v7.1.x or something like v5.6.x or higher version as we have tested.

However with regard to your original issue, this warning are coming from the core WordPress files. Usually when the variable is unset or null, it returns the warning message. Somehow, it is related to this issues:
https://core.trac.wordpress.org/ticket/42860
https://core.trac.wordpress.org/ticket/42814

According to the milestone, it will be resolved in WordPress 4.9.5

Thanks for understanding!
