Ive downloaded all my store files and database. The store successfully shows up on xampp windows service however when I try to login to my admin this is the error I get:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp1\xampp\htdocs\store\admin\includes\classes\logger.php:126) in C:\xampp1\xampp\htdocs\store\includes\functions\sessions.php on line 108

Does anyone know I can fix this??
