to solve this, I tryed I want to know about js/build.js - #5 by OhnO395 with no sucess, (the compiled build.js was different and throwing errors), so edited js/build.js localize method as follow
localize:function(t,e){
return void 0!==e?t.hasOwnProperty(e)?t[e]:"":
t.hasOwnProperty($.pkp.app.currentLocale)?t[$.pkp.app.currentLocale]
:t.hasOwnProperty($.pkp.app.primaryLocale)?t[$.pkp.app.primaryLocale]
:t.hasOwnProperty('pt_BR')?t['pt_BR']
:t.hasOwnProperty('es_ES')?t['es_ES']
:t.hasOwnProperty('it_IT')?t['it_IT']
:t.hasOwnProperty('en_US')?t['en_US']
:""},
there must be anything than an empty string for article title, as it is a required field
