Maybe, try to republish your link to the events list or re-save it...

Do you have empty your cache from joomla ?

and, is it possible to have a link ?

You have other links that don't work (eg. www.amessardegna.it/attivita/coro-voci-dell-isola)

Then, it's not normal that you don't have an alias in your menu "Eventi".
www.amessardegna.it/?Itemid=112 should be www.amessardegna.it/eventi

You have a problem with your menu-link... Try to trash it, and create a new one


EDIT: Your contatti link doesn't work too, with the same problem. It may be a problem with your htacess file (is it present as .htacess on your server ?)

Ho riassegnato al pulsante la funzione di "lista eventi"....
Magari aggiornando il programma da 1.2.9 a 2.0.3 qualcosa non è andato a buon fine..?
Grazie Lyr!c

I've tested the update from 1.2.9 to 2.0.X, but it was a difficult developpement to do, so i may have miss something... (but i don't think that was your problem)
So, there can have some little problems, but most can be solved easily.
Nice if now, this is solved for you !

The developpement of version 2 was very hard work for me, but i'm happy with the result, and with all the new possibilities for the future!
