Проблема с админкой…

При установке над формой пишет:

Warning: Cannot modify header information — headers already sent by (output started at L:\home\localhost\www\block\wp-config.php:1) in L:\home\localhost\www\block\wp-admin\install.php on line 36
установка успешна, копирую админ пасс в буффер!

После установки пытаюсь зайти в админ. часть выдает:
