Installation / Einloggen funktioniert nicht

Hallo,

ich habe auf meinem Server (alfahosting) schon öfter eine Worlpress-Seite ohne Probleme installiert.

Jetzt, nach dem hochladen, bei der install.php erscheint oben schon folgender Fehler:

Warning: Cannot modify header information - headers already sent by (output started at /var/www/web954/html/ESSENonpaper/formart2/wp-config.php:1) in /var/www/web954/html/ESSENonpaper/formart2/wp-admin/install.php on line 57

Wenn ich dann die Daten eingebe und mich einloggen will, kommen folgende Fehler und ich kann mich nicht einloggen:
