I'm running Zoneminder 1.25 on a Alix 1d/Ubuntu Server. Everything worked well until I installed additionally the GUI for Asterisk. If I'm trying to logg in and enter the credentials as always, I receive a message HTTP error page not found 404 and '/undefined' is added to the URL . Any idea what I'm doing or what I have done wrong? THanks in advance for whatever hint provided!
