"Please note, this has to be put before wp-settings.php inclusion" – means what?

Near the bottom of the file, there is a line of code that should look like this:

require_once(ABSPATH . 'wp-settings.php');

That line is the wp-settings.php inclusion referenced in the article. You just need to make sure you are adding the new line of code BEFORE this line, not after it.

Thanks @chad. Awesome answer!

Any time ??
