It was really a stupid question : I forgot to reload the apache server !!!! please discard sorry for the noise Regards Philippe being a newbie, I will certainlt ask a stupid question As a service provider we are evaluating oTRS +ISTM , whihc , at least on paper, seems to fullfill our requirements ( replacement of an old ticketing system , non ITIL) but starting to play with it, I encounter difficulties to do some customisation: for exempal, I try to re-activate the Free Text field in the ticket view, ( menu has disappear following the ISTM installation) . In order to do so , I have re-activated * Ticket::Frontend::MenuModule###310-FreeText * Frontend::Module###AgentTicketFreeText in TicketITSMTicket.xml Then relogin in OTRS but without visible result ( the menu bar still do not display the "FreeField" item, and stay with the "ITSM Field" itme ( which is normal , by the way ) SO the dumb question, is how to have the application to take in account these changes. I though the xml files were parsed at each connection to OTRS ? Thanks in advance Best regards Philippe
