I updated from to 1.9.2.

After that first a SQL error showed up, admin panel was still working. So I decided to do: renew index management and clear cache.

Then it was working again, a few minutes later problem came.

Fatal error: Class 'Mage_Core_Model_App' not found in /var/www/clients/client1/web1/web/app/Mage.php on line 670

Anyone know how to solve this?


Disable the Compiler (uncomment in /your-magento/includes/config.php) Clear the Cache (Browser+Magento) Log in and out

  • Hi TonkBerlin, thanks for your reply. I have no longer acces to admin panel :( on FTP /web/included/config.php is the right file? TKS! I will post down the text in next message. – Chris Jul 7 '15 at 23:52
  • #define('COMPILER_INCLUDE_PATH', dirname(FILE).DIRECTORY_SEPARATOR.'src'); define('COMPILER_COLLECT_PATH', dirname(FILE).DIRECTORY_SEPARATOR.'stat'); – Chris Jul 7 '15 at 23:56
  • make a # in your second line which begins with "define..." – TonkBerlin Jul 8 '15 at 0:02
  • Not working: #define('COMPILER_INCLUDE_PATH', dirname(FILE).DIRECTORY_SEPARATOR.'src'); #define('COMPILER_COLLECT_PATH', dirname(FILE).DIRECTORY_SEPARATOR.'stat'); When: define('COMPILER_INCLUDE_PATH', dirname(FILE).DIRECTORY_SEPARATOR.'src'); #define('COMPILER_COLLECT_PATH', dirname(FILE).DIRECTORY_SEPARATOR.'stat'); – Chris Jul 8 '15 at 0:03
