In the website: ciig.it there is a 706 Kunena  installation on Joomla 6 and Astroid Framework. The website is new and all menus are working instead of "Create new Topic" ina only one category. I set permissions as manual; I have set all to be working. But there is an error:403 Forbidden : Non hai i permessi per avviare una nuova discussione! %sNon è possibile visualizzare questa pagina, potrebbe essere a causa di:

1. un bookmark/preferiti scaduto
2. una ricerca attraverso il motore di ricerca che ha una indicizzazione non aggiornata di questo sito
3. JERROR_LAYOUT_MIS_TYPED_ADDRESS
4. non hai accesso a questa pagina
5. la risorsa richiesta non esiste.
6. si è verificato un errore durante l'esecuzione della richiesta.

Se persistono delle difficoltà, contatta l'Amministratore di questo sito e riporta l'errore

I write the English version:
403 Forbidden: You do not have permission to start a new thread! %s
This page cannot be viewed. This could be due to:

an expired bookmark/favorite
a search using a search engine that has outdated indexing for this site
JERROR_LAYOUT_MIS_TYPED_ADDRESS
You do not have access to this page
The requested resource does not exist.
An error occurred while processing the request.
If you continue to experience difficulties, contact the administrator of this site and report the error.

I am getting a 403 forbidden error on my new topic menu page403 Forbidden : You do not have permissions to start a new topic! Or you haven't created/published a top level category !You may not be able to visit this page because of:

1. an out-of-date bookmark/favourite
2. a search engine that has an out-of-date listing for this site
3. JERROR_LAYOUT_MIS_TYPED_ADDRESS
4. you have no access to this page
5. The requested resource was not found.
6. An error has occurred while processing your request.

I have check permissions and can not find where it specifies who can add a new topic.  I have created a top-level category, and it is the default for all users.  What have I missed?
