in site 1 , we did't installed security patches, but in site 2 we installed security patches.
after copying the folder,
i am getting the error as follows :
Fatal error: Class 'Mage_Install_Controller_Router_Install' not found in /var/www/html/1/10/sitename/app/code/core/Mage/Core/Controller/Varien/Front.php on line 138
but i am new to ssh.
