we are setting Frontend default language to "fa" (persian language)
and "EN" is second language.
but always in first visit (without history and cache and in all browsers in PC or mobile,...) shows frontend with "EN" Language.
we was searching this issue in forum and tested many of methods to resolve this problem (like; some change in fn.init.php) but could not fix it yet.
notice: most of the methods in forum were for old versions of cs-cart.
what should we do?
