Fehlermeldung nach Installation

Hej

Ich habe Drupal installiert. Leider hatte mein Provider während der Installation wohl einige Probleme wie ich im Nachhinein erfuhr.

Nun bekomme ich laufend Fehlermeldungen. Blickt da jemand durch ???

* Warning: Cannot modify header information - headers already sent by (output started at /hsphere/local/home/jmgse/den-tyska-hustomte.se/drupal/includes/common.inc:2561) in drupal_send_headers() (line 1040 of /hsphere/local/home/jmgse/den-tyska-hustomte.se/drupal/includes/bootstrap.inc).
