we enabled compiler in backend. If you set to enabled then the file /includes/config.php changes to
define('COMPILER_INCLUDE_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR.'src'); #define('COMPILER_COLLECT_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR.'stat'); Now I see some posts also about uncommeting the second line http://www.expertwebadvisor.com/manually-enable-disabled-the-compiler-in-magento/
question: but what does COMPILER_COLLECT_PATH do? and why is it not uncommented when I enable compile?
Many thanks
