I see these 4 lines in the .htconfig.php :
// Uncomment the following 4 lines to turn on PHP error logging.
//error_reporting(E_ERROR | E_WARNING | E_PARSE );
//ini_set('error_log','php.out');
//ini_set('log_errors','1');
//ini_set('display_errors', '0');
How can enable the error logging and provide the location of the log file?
