on Saturday we changed our server from Gentoo XEN Dom0, CentOS 4.4 DomU to CentOS 5 Dom0, CentOS 5 DomU. (Followed Network Edition Disaster Recovery in the wiki)

Today a customer told me, that the Zimbra Web GUI is alwasy on German no matter which language is chosen in the browser configuration. No chance to get it in English.

I just installed the German translations like I always do after an update.

Perhaps the problem is due to the fact that the centos5 is German, too?

Release 4.5.6_GA_1044.RHEL5_20070706163724 CentOS5{i} NETWORK edition
