Horde language selection does not work

Filed under: Linux,Server Administration — Tags: , , , , , , , , — Christopher Kramer @ 13:22

When selecting a language at login, Horde webmailer does not change the language?

Here is what I found out what helps:

On Debian, run the following command:

dpkg-reconfigure locales

Then select the correct languages. I had only selected the UTF8 languages for German, but Horde needs the following ones:

de_DE ISO-8859-1
de_DE@euro ISO-8859-15

If you have the problem with another language, select the corresponding language.

On Ubuntu, the chosen languages are stored here:


I had a file named “de” in there where my chosen languages where listed and I added the ISO-versions above. You can find all supported languages here:

less /usr/share/i18n/SUPPORTED

On Ubuntu, after you included your languages, you have to run the following command:

dpkg-reconfigure locales

Afterwards, you need to restart apache:

apache2ctl -k graceful

That’s the smoothest way. In case it does not work, use one of those:

apache2ctl restart
service apache2 restart
/etc/init.d/apache2 restart

Now refresh Horde and everything should work.

Another problem is the following: if you chose a language in your Horde settings (login, Global Options, Locale and time, Select your preferred language), this overwrites the language you chose on login. So select “default” there to be able to chose language on login.

Hope this helps somebody.
