Why is the $_POST array left empty?

Question

1C-Bitrix

What could be the reasons why after submitting the form $_POST is empty? And how to find these reasons?

<form method="post" action="<?=$arParams['CONFIRM_URL']?>" name="regform" enctype="multipart/form-data">

This is a string from the bitix component template. After submitting this form, there is nothing in the POST.

somewhere the post request is being cleaned. search in result_modifiers.php/init.php
explore the entire path to the component. learn how to use xdebug
