G5 timezone 에러 채택완료

서버에 있던걸 pc xampp 로 옮겼습니다.

그리고 실행을 하니 

Warning: Use of undefined constant G5_TIMEZONE - assumed 'G5_TIMEZONE' (this will throw an Error in a future version of PHP) in C:\xampp\htdocs\kr\common.php on line 141

Warning: Use of undefined constant G5_THEME_PATH - assumed 'G5_THEME_PATH' (this will throw an Error in a future version of PHP) in C:\xampp\htdocs\kr\common.php on line 487

Warning: Use of undefined constant G5_THEME_PATH - assumed 'G5_THEME_PATH' (this will throw an Error in a future version of PHP) in C:\xampp\htdocs\kr\_st\core\ST_Theme.php on line 14

이렇게 에러를 뱉어내는데 이런건 첨이라서..

어디를 어떻게 손봐야 하나요?
