Does anybody have solution for this? As cadillackid did, I already went into manage forms and ticket details and unchecked editing of the ticket editing by agents. Also unticked the permission to edit thread and edit ticket, as suggested by Micke1101, yet the agent can still edit his/her own response. Each entry still has the dropdown box for editing a response by the agent. Is it a bug? I use osTicket-v1.10.1.Or does anybody know how to permanently remove the dropdown box for editing, by modifying the ticket.php ?Regards,Aswad
