Language Configuration
In normal cases, ownCloud will automatically detect the language of the Web-GUI. If this does not work as expected, or you want to make sure that ownCloud always starts with a given language, you can use the default_language configuration parameter.
This parameter can be set in config/config.php
Parameters
'default_language' => 'en',
Please keep in mind, that this will not effect a users language preference, which can be configured under
once he has logged in.More supported languages can be found in directory <ownCloud_root>/settings/l10n. List all files with ls *.js. The language code to be used is the filename without extension.
Example:
en_GB.js --> en_GB
Please see Wikipedia for a match of language code to country.
