LiquidFiles comes with English translation as default. All other translations comes from users such as yourself that want the LiquidFiles appliance in other languages and are willing to share with others. If you are native Arabic speaker feel free to create that translation in "Admin > System > Locales", then export the language files and share here on the forum with other users. https://forum.liquidfiles.com/threads/additional-languages.531/
thanks for your response, ok got it well i need only user can see Arabic but admin can see in English, is it possible ?????
yes, this is basically only option in LF appliance. The Admin interface does not support other translations, only English. The interface for translations (Admin > System > Locales) covers texts only for the User web interface.
