Help solve the issue with sending the form from the site to the email address.

  1. I have enabled mail sending: cPanel > Settings > General > Sendmail > On
  2. I have not exceeded mail sending quota (50 emails/day)
  3. Form code on the page:
<div class="col-xs-12 col-md-8">
                        <div class="contact-form">
                            <form action="process.php" id="contact-form" method="post">
                                <div class="form-double">
                                    <input type="text" id="form-name" name="form-name" placeholder="Ваше ім'я" required="required">
                                    <input type="number" placeholder="Номер телефону">
                                </div>
                                <div class="form-double">
                                    <input type="email" name="form-email" name="email" id="form-email" placeholder="Електронна пошта" required="required">
                                    <input type="text" name="form-subject" id="form-subject" placeholder="Тема" required="required">
                                </div>
                                <textarea name="form-message" id="message" id="form-message" rows="5" required="required" placeholder="Текс попідомлення"></textarea>
                                <button class="bttn bttn-primary">Надіслати</button>
                            </form>
                        </div>
                    </div>
