Answer 1

您需要在应用程序中更早地启动会话。从您的堆栈跟踪中，我可以看到您正在调用扩展 BootstrapAbstract 的后端引导文件。要修复此错误，您可以在该文件中初始化会话。请注意，引导文件中的任何 _init 方法都会自动调用。

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initSession()
    {
        // do any extra session config here
        Zend_Session::start();
    }
}

Answer 2

尝试在Plugins_AccessCheck 类中的routeStartup 函数中移动有关会话的代码，如下所示：

public function routeStartup(Zend_Controller_Request_Abstract $request)
{        
    //*******************************
    // Checking License
    //******************************

    $licence_error = new Zend_Session_Namespace('licence_error');

    if (!$licence_error->active === NULL) {
        throw new Exception('Licence Error', 404);
    }
}
