It’s working but there’s an error with “sizeof()”

Hi Alopex91,

We will note it down for our future releases.

But warning and notice errors should not be displayed in your site. It should be disabled in live site. It will be enabled only in the development stage.

Please check this article on how to disable it: https://www.wpbeginner.com/wp-tutorials/how-to-turn-off-php-errors-in-wordpress/

Regards.
