#3 app/code/core/Mage/Core/Model/Mysql4/Collection/Abstract.php(118): Mage_Core_Model_Mysql4_Abstract->getMainTable()

 

Cause

Cannot retrieve entity config: core/store_group error message means that default Magento configuration can not be inited on your installation.

It can happen if you accidentally moved/deleted files in app/code/core/Mage/Core directory, app/code/core/Mage/Core/Helper/etc for example.

 

Solution

  • Check that app/code/core/Mage/Core/etc exists and is not corrupted. Check other files under app/code/core/Mage/Core or restore it from the backup or original Magento distribution.
  • Flush Magento caches and disable Compiler (if it was enabled) or simply move includes directory out.
