Данные формы веб-сайта перестают сохраняться в таблице Google со вчерашнего дня, т.е. 26/05/2015

Я создал приложение, в котором данные формы моего веб-сайта будут храниться в электронной таблице Google. До вчерашнего дня все работало нормально, то есть 26.05.2015. Но с сегодняшнего дня, то есть 27.05.2015, он внезапно перестал работать. И никакая ценность не добавляет в электронную таблицу Google.

Я использовал указанный ниже класс для работы с электронными таблицами

spreadsheet.php:

<?php

class spreadsheet {
private $token;
private $spreadsheet;
private $worksheet;
private $spreadsheetid;
private $worksheetid;

public function __construct() {
}

public function authenticate($username, $password) {
$url = "https://www.google.com/accounts/ClientLogin";
$fields = array(
"accountType" => "HOSTED_OR_GOOGLE",
"Email" => $username,
"Passwd" => $password,
"service" => "wise",
"source" => "pfbc");
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $fields);
$response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);

if($status == 200) {
if(stripos($response, "auth=") !== false) {
preg_match("/auth=([a-z0-9_\-]+)/i", $response, $matches);
$this->token = $matches[1];
}
}
}

public function setSpreadsheet($title) {
$this->spreadsheet = $title;
}

public function setWorksheet($title) {
$this->worksheet = $title;
}

public function add($data) {
if(!empty($this->token)) {
$url = $this->getPostUrl();
if(!empty($url)) {
$headers = array(
"Content-Type: application/atom+xml",
"Authorization: GoogleLogin auth=" . $this->token,
"GData-Version: 3.0");

$columnIDs = $this->getColumnIDs();
if($columnIDs) {
$fields = '<entry xmlns="http://www.w3.org/2005/Atom" xmlns:gsx="http://schemas.google.com/spreadsheets/2006/extended">';
foreach($data as $key => $value) {
$key = $this->formatColumnID($key);
if(in_array($key, $columnIDs))
$fields .= "<gsx:$key><![CDATA[$value]]></gsx:$key>";
}
$fields .= '</entry>';

return "";
}

private function formatColumnID($val) {
return preg_replace("/[^a-zA-Z0-9.-]/", "", strtolower($val));
}
}

?>

и использовать его следующим образом:

включите «spreadsheet.php»;

$doc = new spreadsheet();
$doc->authenticate("[email protected]", "example");
$doc->setSpreadsheet("Tester");
$doc->setWorksheet("Sheet1");
$my_data = array("First Name" => "John", "Last Name" => "Doe");
$doc->add($my_data);

Пожалуйста, помогите мне. Заранее спасибо.
