405 HTTP Error on submitting data on PHP / HTML form

Question

I am building a form that the filled data need to be sent to an email. I am using HTML and PHP. But Unfortunately I get the following error when I press SUBMIT button.

405 - HTTP verb used to access this page is not allowed. The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access

The PHP code is:

 <?php if (isset($_POST['submit'])) { $name = $_POST['name']; $visitor_email = $_POST['email']; $message = $_POST['message']; $email_subject = "NEW MESSAGE VIA CONTACT FORM"; $email_body = "You have received a new message from the user ".$name. ".\n".$message; $to = "info@house.gr" $headers = "From: ".$visitor_email; mail($to, $email_subject, $email_body, $headers); header("Location: index.html?mailsend"); }?>

The HTML form is:

 <form method="POST" class="contact-form" actions="contactform.php"> <input type="text" name="name" placeholder="Full Name"> <input type="text" name="mobile" placeholder="Your Mobile Phone"> <input type="text" name="email" placeholder="Your E-mail"> <textarea class="materialize-textarea" name="message" placeholder="Your Message"></textarea> <input type="submit" value="Submit" class="btn"> </form>

UPDATE: with this edit on code: action="contactform.php", I dont get the error but the email is not send

Answer 1

maybe you wrote actions instead of action in the form's attribute

actions="contactform.php"

should be

action="contactform.php"

Answer 2

which web server you are using
