Hello all, Gerald, I corrected some conf and the script succeeded. Unfortunately, it was not enough. After some backup of my conf files, I uninstalled all the apache2 (v2.2.22) packages (dpkg -l | grep apache2 ) with apt-get purge transfered the v2.2.20 packages from other system (I found them in /var/cache/apt/archives) then installed those. After putting back the otrs.conf file in /etc/apache2/conf.d and restart apache2 >> it works. Conclusion: the v3.0 I have does not run well on apache 2.2.22, behaves ok on 2.2.20 Thank again for your time Best Regards Jerome
