Hello,I think I found the problem: in my database, in the `ost_ticket_status` table, the key 'Resolved' with status 'resolved'.It appears that this state does not exist!To correct, here is the solution:Open -> openResolved -> closedClosed -> closedArchived -> archivedDeleted -> deletedI hope it will stay functional ...On the other hand, I do not understand who could have changed this state ...Regards
