Hello :-) Sorry -- I accidentally sent the earlier mail as HTML so am resending in plain text. After using 3.0.7's UPGRADING instructions to upgrade from 3.0.7 to 3.0.8 (fromotrs-3.0.8.tar.gz), the OTRS logon page displayed "the browser you are using is too old". /var/log/apache2/error.log pointed to an OTRS permissions problem. root@system:~# ls -l /opt/otrs/var/ total 44K drwxrwsr-x 2 otrs www-data 1 May 24 13:54 article drwxr-xr-x 2 500 users 88 May 24 13:54 cron drwxr-xr-x 2 500 users 64 May 24 13:54 fonts drwxr-xr-x 3 500 users 8 May 24 13:54 httpd drwxrwsr-x 2 otrs www-data 8 Jun 1 15:02 log -rw-r--r-- 1 500 users 24K Oct 26 2010 logo-otrs.png drwxr-xr-x 2 root root 16 May 24 13:54 packages drwxrwsr-x 2 otrs www-data 1 May 24 13:54 sessions drwxrwsr-x 2 otrs www-data 1 May 24 13:54 spool drwxrwsr-x 2 otrs www-data 4.0K May 24 13:54 stats drwxrwsr-x 4 otrs www-data 32 Jun 1 15:04 tmp The installation procedure used was compared with the 3.0.7 fresh installation procedure and was identical except for copying the old Config.pm, GenericAgent.pm and ZZZAuto.pm files. Here is the exact procedure used (sorry about any line-wrapping): root@system:~# /etc/init.d/cron stop; /etc/init.d/apache2 stop root@CW8vDS:~# old_ver=3.0.7; new_ver=3.0.8 root@system:~# dir=/var/opt/otrs/backup/$old_ver; mkdir -p $dir && chown otrs:otrs $dir \ && /opt/otrs/scripts/backup.pl -d $dir root@system:~# mv /opt/otrs /opt/otrs-$old_ver root@system:~# cd /opt && tar -xzf /root/Repository/otrs-$new_ver.tar.gz \ && ln -s otrs-$new_ver/ otrs root@system:/opt# cd /opt \ && cp -p otrs-$old_ver/Kernel/Config.pm otrs-$new_ver/Kernel/ \ && cp -p otrs-$old_ver/Kernel/Config/GenericAgent.pm otrs-$new_ver/Kernel/Config \ && cp -p otrs-$old_ver/Kernel/Config/Files/ZZZAuto.pm otrs-$new_ver/Kernel/Config/Files/ root@system:/opt# cd /opt/otrs/ \ && bin/otrs.SetPermissions.pl --otrs-user=otrs --otrs-group=otrs \ --web-user=www-data --web-group=www-data /opt/otrs root@system:/opt/otrs# cd /opt/otrs/ \ && bin/otrs.RebuildConfig.pl \ && bin/otrs.DeleteCache.pl root@system:/opt/otrs# /etc/init.d/cron start; /etc/init.d/apache2 start It would probably be OK to set ownerships/permissions the same as 3.0.7 but would be time-consuming and error prone; better to fix whatever I did wrong. P.S. This is on a Debian Squeeze 64-bit system. Best Charles
