Thema: Canonicalization schlug fehl - Seite down

Ich habe gestern Abend einen großen Fehler gemacht. Im Canonicalization-Plugin habe ich eine Umlaut-URL eingegeben - ja inklusive Umlaut. Ich denke mal das ist das Problem, weil seit dem meine Seite http://stephan-müller-foto.de/ nicht mehr erreichbar ist und immer angezeigt wird:
Der Server unter www.stephan-m%c3%bcller-foto.de konnte nicht gefunden werden.
Wo hat das Plugin den Canonical-Tag eingefügt damit ich ihn manuell per FTP ändern kann? Hat das auch was mit der .htcaccess zu tun? Die sieht derzeit so aus:
