Login funtkioniert nicht (Fehlermeldungen)

Hallo allerseits, ich habe mir eine Webseite mithilfe von Wordpress eingerichtet. Als ich mich dann anmelden wollte kamen folgende Fehlermeldungen:

Warning: Cannot modify header information - headers already sent by (output started at /users/myblogspot/www/Start/wp-config.php:1) in /users/myblogspot/www/Start/wp-login.php on line 418

Warning: Cannot modify header information - headers already sent by (output started at /users/myblogspot/www/Start/wp-config.php:1) in /users/myblogspot/www/Start/wp-login.php on line 431

Ich frage mich jetzt, was es da zu meckern gibt, weil ich nichts verändert habe. In den Zeilen 418 und 431 von wp-login steht folgendes:

418 header('Content-Type: '.get_bloginfo('html_type').'; charset='.get_bloginfo('charset'));


431 setcookie( TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN, $secure );

und in pluggable das hier

Ab 913


setcookie($auth_cookie_name, $auth_cookie, $expire, PLUGINS_COOKIE_PATH, COOKIE_DOMAIN, $secure, true);
setcookie($auth_cookie_name, $auth_cookie, $expire, ADMIN_COOKIE_PATH, COOKIE_DOMAIN, $secure, true);
setcookie(LOGGED_IN_COOKIE, $logged_in_cookie, $expire, COOKIEPATH, COOKIE_DOMAIN, $secure_logged_in_cookie, true);


Danke schonmal!
