We have not installed m2epro through magento connect, hence we couldn't upgrade M2epro. M2epro support team adviced to remove following file and install using Magento connect.
'app/code/community/Ess/M2ePro', 'app/design/adminhtml/default/default/layout/M2ePro.xml', 'app/design/adminhtml/default/default/template/M2ePro', 'app/etc/modules/Ess_M2ePro.xml', 'js/M2ePro', 'skin/adminhtml/default/default/M2ePro', 'skin/adminhtml/default/enterprise/M2ePro'
After clearing cache we try to install M2epro using Magento connect, we were getting 'couldn't connect to host' error.
Here is the extension link we used; http://connect20.magentocommerce.com/community/m2epro_ebay_magento After that we give permission and installed M2epro. Cleared all cache manually and restored permission. Now we can't log into admin side. We are getting following error.
"Fatal error: Call to a member function setActive() on a non-object in '/var/www/site/public_html/app/code/core/Mage/Adminhtml/Controller/Action.php on line 96"
Please let us know how we can fix this.
