Перестало работать) #16

Добрый день. Меня зовут Евгений. У нас работала синхронизация на сайте с продуктам 1с.
Два месяца назад она перестала работать. Выяснили что подключение есть, но сайт информацию не отдает. Изучали код и предположили следующую ошибку. В коде написаны не рабочие ссылки на ресурсы.
Вот часть кода:

function setCapabilities()
{
// Initialises capabilities array
$this->capabilities = array(
'xmlrpc' => array(
'specUrl' => 'http://www.xmlrpc.com/spec',
'specVersion' => 1
),
'faults_interop' => array(
'specUrl' => 'http://xmlrpc-epi.sourceforge.net/specs/rfc.fault_codes.php',
'specVersion' => 20010516
),
'system.multicall' => array(
'specUrl' => 'http://www.xmlrpc.com/discuss/msgReader$1208',
'specVersion' => 1
),
);
}

Мы очень слабо разбираемся в программировании, но предполагаем, что при рабочих ссылках всё заново будет работать.

Это весь код:

    $length = strlen($xml);
    header('Connection: close');
    header('Content-Length: '.$length);
    header('Content-Type: text/xml');
    header('Date: '.date('r'));
    echo $xml;
    exit;
}

function hasMethod($method)
{
    return in_array($method, array_keys($this->callbacks));
}

function setCapabilities()
{
    // Initialises capabilities array
    $this->capabilities = array(
        'xmlrpc' => array(
            'specUrl' => 'http://www.xmlrpc.com/spec.md',
            'specVersion' => 1
    ),
        'faults_interop' => array(
            'specUrl' => 'http://xmlrpc-epi.sourceforge.net/specs/rfc.fault_codes.php',

}

function listMethods($args)
{
    // Returns a list of methods - uses array_reverse to ensure user defined
    // methods are listed before server defined methods
    return array_reverse(array_keys($this->callbacks));
}

function multiCall($methodcalls)
{
    // See http://www.xmlrpc.com/discuss/msgReader$1208
    $return = array();
    foreach ($methodcalls as $call) {
        $method = $call['methodName'];
        $params = $call['params'];
        if ($method == 'system.multicall') {
            $result = new IXR_Error(-32600, 'Recursive calls to system.multicall are forbidden');
        } else {

• It is intended to assist in organization of your XML-RPC methods by allowing
