Stephanie 1 Report post Posted June 8, 2020 After Updating to M2ePro 6.6.0 (Magento 1.9.4.5) we are not able to generate credit memos. In the error logs I can see, that there is a problem with loading several models via Mage::getModel. PHP message: PHP Fatal error: Uncaught Error: Call to a member function handle() on boolean in /app/code/community/Ess/M2ePro/Observer/Creditmemo.php:47 The Model Ess_M2ePro_Model_Amazon_Order_Creditmemo_Handler can not be instantiated. In the file config.xml there is a part where the models are defined and it seems due to this change the models can not be created. <!-- Observer dir. was moved outside of Model dir. --> <M2ePro_Observer> <class>Ess_M2ePro_Observer</class> </M2ePro_Observer> Is anybody facing the same issues after the update? Thanks, Stephanie Quote Share this post Link to post Share on other sites

maxxx676 0 Report post Posted July 29, 2020 Hi, I faced the same error before. It was related to the name of CreditMemo folder in my Magento, it should be named 'Creditmemo'. But it also can be related to some files missing in your instance. You can try upgrading M2E Pro to the latest version and check the issue afterward.
