Quickbooks PHP API(整合版).连接错误

我已经使用这个几个月了，但是突然开始出现错误。我重新生成了QB键，但它仍然发生

当我运行任何东西时，我首先包含配置文件

include 'quickbooks-php/docs/partner_platform/example_app_ipp_v3/config.php';

在配置文件中，脚本总是在这一行失败:

if ($IntuitAnywhere->check($the_username, $the_tenant) and 
    $IntuitAnywhere->test($the_username, $the_tenant)){

错误如下:

<b>Notice</b>:  unserialize(): Error at offset 0 of 4 bytes in <b>/var/www/html/quickbooks-php/QuickBooks/Encryption/Aes.php</b> on line <b>82</b><br />
<br />

我尝试运行diagnostics.php并收到相同的错误。

如果Keith(以前帮助过我的作者)或其他人能帮助我，我将不胜感激。官方论坛似乎很低迷。
