php form action not working

These codes work with phpMailer. There is no reaction to butona press. why could it be? Do you have a suggestion? I ran the code on a blank project without including it in the project. I did not find any problems. I do not understand whether there is a mistake in the form.

index.php my home page

<?php include 'includes/header.php'; ?>
<?php include 'includes/slider.php';?>
<?php include 'includes/onepage-home.php';?>
<?php include 'includes/footer.php';?>

onepage-home.php contact form page

<div class="col-md-6 no-padding">
                <div class="contact-forms">
                    <form class="b-form b-contact-form home-contact-form" method="post" action="../send.php">

            <div class="row">
