Versione: 2.8.0beta1

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.**

A meno che tu non riesca a riprodurlo qui (prova a cambiare la categoria di questo argomento, o del tuo argomento, da “bug” a qualcosa di diverso), non si tratta di un bug, ma di un problema di configurazione sul tuo sito.

Stesso problema qui:

 ![image](https://global.discourse-cdn.com/meta/original/3X/8/8/881eef20df6db3ba6cb2e5dae20fac9187fa10cf.png)

@codinghorror: Scusa, non sono molto d’accordo con la definizione di bug nel dominio di Discourse. Per me sembrava un bug, dato che non ho apportato alcuna modifica al nostro sito. Tuttavia, riesco a riprodotlo anche qui, il che non significa comunque che sia un bug..

Posso riprodurlo qui:

Chrome: Versione 89.0.4389.90 (Build Ufficiale) (x86\_64)

1. Aggiorna la pagina
2. Clicca su modifica titolo
3. Premi Salva (senza apportare modifiche)
4. Messaggio di errore JavaScript.

@codinghorror: Va bene riportarlo come bug?

</div>

Ok, quindi l’errore si verifica quando avvii la modifica del titolo nel primo post, ma non apporti effettivamente alcuna modifica e premi salva? Fammi provare… sto per modificare…

Ah sì, riesco a riprodurlo. Grazie per la segnalazione, è effettivamente un bug di qualche tipo @zogstrip. Quando modifichi il titolo dell’argomento o la categoria tramite il pulsante di modifica accanto al titolo dell’argomento, ma non apporti modifiche e premi poi salva, si verifica quanto descritto da @dirien.

@cvx puoi aggiungerlo alla tua lista?
