daryl@softwaremajor.com 0 Report post Posted September 22, 2016 Hi Right after installation of M2E Pro, on both front and back ends, Magento fails with this error: PHP Fatal error: Class 'Ess_M2ePro_Model_Upgrade_MySqlSetup' not found in /var/www/httpdocs/includes/src/__default.php on line 7621 I can see that this class exists in app/code/community/Ess/M2ePro/Model/Upgrade/MySqlSetup.php, so I am guessing there might be something missing in an XML file someplace. Any ideas? Daryl Quote Share this post Link to post Share on other sites
