I installed CB 1.1 and the german language files (f+i) in Joomla 1.5 Stable, but the language doesn't change to german (Default). I also tried to overwrite the default-language folder like described in this forum but it didn't worked right (strange parameter-names in regsitration and everywhere else).
für Joomla 1.013 + CB1.1 das language download "German language pack 1.01" runterladen und nicht "German Formal..."
dann (ohne Gewähr) im Plugin Manager default language english auf order -1 setzen und German auf z.b. 99.
Funktioniert bestens bei mir.
Have the same problem
I'v installed Joomla 1.0.15de and CB1.1 with cb_1.0.1_german but no tips in this forum will work... i think the last way is to hardcode the default_language
