I knew that but i use RVskin which automatically select the language of Softaculous so that do not work for me as i have to also edit the Spanish language and need both called by default English and Spanish, if this is the only way that Softaculous language can be overwrite you have to seriously work out something else guys. As many other product perhaps creating an "overwrite" directory into the language directory so any language file variables modified on it have precedence.
