Question Seo Urls geht nicht

Hallo,

wenn ich in der Joomla- Konfiguration SEO freundliche URLS aktiviere, kann ich keine Topiclinks mehr aufrufen und die bekannte 404 von Joomla kommt.
Wenn ich aber die SEO freundlichen URLS deaktiviere funktioniert alles bestens!
An was kann das liegen?

In mein Main-Menü (nicht in Kunena-Menü) habe ich ein Navigationspunkt "Forum" welches als externe Url auf "index.php?option=com_kunena&catid=2&view=category" verlinkt ist. Ich wollte den Menüeintragstyp von "externe Url" auf "Kategorie anzeigen (Kunena)" wechseln (da ich dachte deshalb der Fehler), aber dort wo ich die Kategorie- ID eingeben soll gibt es kein Inputfeld.

Ich hoffe auf eure Hilfe.

edit: Wenn ich wiederum Joomsef aktiviere geht zwar alles aber die Buttons für die Moderation gehen nicht (bearbeiten, genehmigen, löschen etc..), dort kommt immer 404

Lösche in deinem Hauptmenü den Menüpunkt welcher zum Forum führt. Den ursprünglich funktionierenden hast du in deinen Papierkorb verschoben und stattdessen diesen falschen Menüpunkt erstellt.
