[otrs] OTRS 3.1.7 on Debian 6

Hi, i move my otrs environment from windows server to a debian server. On windows, after edit of the kernel/config.pm, i have to run a script to restart apache, cron, mysql. After the installation of otrs on debian, i see that the software reload automaticaly the changes... but now at the end of migration, it seems not work. Test 1: manual restart of cron, apache --> failed, config.pm not reloaded Test 2: manual stop of cron, apache; run script bin/otrs.RebuildConfig.pl and bin/otrs.DeleteCache.pl; manual start of cron apache -> failed --> failed, config.pm not reloaded Test 3: Test 2 and after a reboot of the debian machine What's my error? In my config.pm i modify a custom ACL rule. thanks for the help -- *Stefano Ricci*
