Eliminazione utente non funziona

[feroda]

Dominique riporta:

non riesco a cancellare questo utente http://ordini.desmacerata.it/gasistafelice/admin/auth/user/299/delete/ che dicono i log?

[feroda]

l'errore avviene nella gestione del segnale di variazione del ruolo di default quando un ruolo viene cancellato. Se l'eliminazione del ruolo (ppr) avviene a seguito dell'eliminazione dell'utente, quando l'handler cerca di resettare il ruolo di default per gli utenti collegati a quel ppr, non lo/li trova e pertanto va in errore.

È sicuro mettere un try/except qui e vado a farlo.

I log dicono:

ERROR Internal Server Error: /gasistafelice/admin/auth/user/299/delete/
