There is a page with a form, when you click on submit, it sends it on the page handler.php, but instead of doing something, it writes:
Страница недоступна Сайт site.com не отправил данных. ERR_EMPTY_RESPONSE It does not work even on a simple example.
<form action="handler.php" method="post"> <input type="text" name="text"> <input type="submit"> </form> handler.php
<?php print_r($_POST); ?>
