Hi all, Sorry to disturb, but I've been trying to upgrade from 2.4.8 to 3.0.4, following this page http://doc.otrs.org/3.0/en/html/upgrading.html, and it seems that it's not working : Software error: Can't load backend module Kernel::System::Cache::File! at /opt/otrs//Kernel/System/Cache.pm line 83. For help, please send mail to the webmaster ([no address given] mailto:[no%20address%20given]), giving this error message and the time and date of the error. Since google is my best friend, he told me to see this http://comments.gmane.org/gmane.comp.otrs.user/32870, which I did, but unfortunately, first I do not know if the answer corrected the trouble, second I do not know where I am supposed to find the config for $home.. Can anybody help? Thank you ps : otherwise, great job guys, this thing is really useful! -- Simon Gareste Support& Development Engineer -- Consortium Scilab Digiteo Domaine de Voluceau Rocquencourt - B.P. 105 78153 Le Chesnay Cedex --
