Здравствуйте.

После переезда на https не работает модуль быстрого заказа.

Код:
 

<?php
    $product_name = trim($_POST['product_name']);
    $product_price = trim($_POST['product_price']);
    $customer_name = trim($_POST['customer_name']);
    $customer_phone = trim($_POST['customer_phone']);
    $customer_message = trim($_POST['customer_message']);
    $mail_subject = "Мой интернет-магазин - предзаказ (".date('d.m.Y H:i').")";
    
    if (isset($customer_name) && $customer_name!=="" && isset($customer_phone) && $customer_phone!=="") {
      $store_email = "@gmail.com";
      $fast_order_email = "@yandex.ua";
      $product_name = iconv("UTF-8", "windows-1251", $product_name);
      $product_price = iconv("UTF-8", "windows-1251", $product_price);
      $subject   = '=?windows-1251?B?'.base64_encode($mail_subject).'?=';
      $customer_name = iconv("UTF-8", "windows-1251", $customer_name);
      $customer_phone = iconv("UTF-8", "windows-1251", $customer_phone);
      $customer_message = iconv("UTF-8", "windows-1251", $customer_message);
      $subject = '=?windows-1251?B?'.base64_encode($mail_subject).'?=';
      $headers = "From: <".$fast_order_email.">\r\n";
      $headers = $headers."Return-path: <".$fast_order_email.">\r\n";
      $headers = $headers."Content-type: text/plain; charset=\"windows-1251\"\r";
      mail($store_email,$mail_subject,"Предзаказ\n\nДата заказа: ".date('d.m.Y H:i')."\nЗаказчик: ".$customer_name."\nТелефон: ".$customer_phone."\nКомментарий: ".$customer_message."\n\nТовар: ".$product_name."\nЦена: ".$product_price,$headers);                               
    } else { 
      echo "empty"; 
    };

 

$(document).ready(function () {
    $('#fast_order').colorbox({href:"#fast_order_form",inline:true, width:"650px", height:"330px", title:" "});
    $('#fast_order_form .fast_order_center button').click(function () {
      var product_name = $('#product_name').val(); 
      var product_price = $('#product_price').val();
      var customer_name = $('#customer_name').val();
      var customer_phone = $('#customer_phone').val();
      var customer_message = $('#customer_message').val();
      $('#result').html('Обрабатываем введенные данные..');
      $.post('/fast_order.php', { 'product_name': product_name, 'product_price': product_price, 'customer_name': customer_name, 'customer_phone': customer_phone, 'customer_message': customer_message }, function (data) { if (data == 'empty') { $('#fast_order_result').html('<span class="fast_order_error">Обязательно укажите ваше имя и телефон, иначе мы не сможем вам перезвонить!</span>'); } else { $('#fast_order_result').html('<span class="fast_order_success">Ваш заказ успешно оформлен!</span><br /><span>Мы перезвоним вам в течение дня. <a onclick="$(window).colorbox.close();">Закрыть</a> это окно?</span>'); } });
    });
});

Помогите пожалуйста с решением.
