About e107 Language support
In the Admin Area -> Settings -> Languages you can manage language (Locales) from here.
e107 supports multi-language for core element text. All core display text is read from a Language Text File which is associated with the specific area of the system. The system reads phrases from this file used as static & message text for the currently selected session language preference. It will return English if not found, or report the missing code something like LAN_CODE_00.
Plugins and Themes also support language if the translation file exists.
Official Language Translations are listed here:-
