Laravel localization

I'm using laravel and mcamara/laravel-localization package to manage multi-language site. When I want to redirect to another route I use url(Lang::getLocale().'/about') which work fine but it has built in method LaravelLocalization::getLocalizedURL('en', '/about') it doubles url "http://localhost:8888/motor2/public/motor2/public/en/about". Any help.
