That is odd. I have no osTicket experience prior to 1.9.2, so I don't know if the upgrade has caused you to run afoul of any system requirements that may have gone up between your 1.8.6 and the current 1.9.4. Maybe someone else here can shed light on that. Meanwhile...Please read before requesting assistanceIf you would provide the requested info on your system, that might help with troubleshooting.Jack
