Fatal error: Class ‘Mage_Core_Model_Resource_Setup’ not found
After upgrading to 1.1.8. everything worked fine. But when I installed the Modern Theme with Magento Connect the site broke (frontend & backend) and I get this: Fatal error: Class ‘Mage_Core_Model_Resource_Setup’ not found in /home/httpd/vhosts/bookabook.nl/httpdocs/app/code/core/Mage/Core/Model/Config.php on line 215.
Line 215 points to the database I guess. I’ve no clue about mysql and cannot find this error in the forums. Can anybody help me out?
