Ciao,

Quando modifico il titolo di un argomento e provo a salvare le modifiche, ricevo il seguente messaggio di errore nella console del mio browser:

 ![image](https://global.discourse-cdn.com/meta/original/3X/2/8/28b78b27bcb0063455396f09127634871393db48.png)

E non riesco a salvare.

**Soluzione alternativa: Se seleziono di nuovo la stessa categoria, funziona correttamente.**
