Hi I'm new to otrs and also out-of-touch with perl. So this could be a simple problem. I've installed latest otrs on a linux, Debian Lenny, from source, carefully followng chap 3.2.1 of the pdf documentation. Now wenn I call http://myserver.mydomain/otrs/installer.pl from the browser I get an "Internal Servr Error, The server encounted an internal error or misconfiguration and was unable to complete your request". The apache2 log file records "Can't locate Kernel/Config.pm in @INC (@INC contains: ...) at /home/www/otrs/bin/cgi-bin/installer.pl line 40." installer.pl line 40 is "use Kernel::Config;" the section over line 40 goes === use strict; use warnings; # use ../../ as lib location use FindBin qw($Bin); use lib "$Bin/../.."; use lib "$Bin/../../Kernel/cpan-lib"; use vars qw($VERSION $Debug); $VERSION = qw($Revision: 1.28 $) [1]; # check @INC for mod_perl (add lib path for "require module"!) push( @INC, "$Bin/../..", "$Bin/../../Kernel/cpan-lib" ); === As you must have noticed otrs is not in /opt but under /home/www. I thought, I was careful in giving that parameter during the installation. Can somebody post instructions where to look? Ratna
