[Koha] production mode - trapped fatal error : huh ??

Hi all, First please excuse my poooooor english :) I'm trying to install Koha 3.00 on the lastest Debian. The perl installer works, no problem. But when I go on the Installer Web page (127.0.1.1:8080) I've got : production mode - trapped fatal error I've taken a look to the log : Can't call method "id" on an undefined value at InstallAuth.pm I'm totally blocked. Someone can help me please ? -- View this message in context: http://www.nabble.com/production-mode---trapped-fatal-error-%3A-huh----tp192...
