Hi Jich,
thank you.......

We have integrated the paid mturbo caching extension for one of our client and we are getting the following error in magento system.log when ever cron is executed, can you please suggest us how to resolve this issue,
Cron is working perfectly for other jobs

Recoverable Error: Argument 1 passed to Artio_MTurbo_Model_Observer::flushQueueCron() must be an instance of Varien_Event_Observer, instance of Mage_Cron_Model_Schedule given in /var/www/venky/app/code/local/Artio/MTurbo/Model/Observer.php on line 454

Your help is highly appreciated,

thanks
