The website is in two languages. There's Portuguese as the primary one at http://www.site.com/, and then there's a link on the top right that sends people to http://www.site.com/eng/, for the English version. The problem is that the English version is very outdated and I don't know how to get there from the back-end.
I've meddled around in [Site > Languages > Site Languages] but there doesn't seem to be any way to get to language's contents. I also can't find any English content anywhere on the back-end. Also, since the English front-end is at http://www.site.com/eng/, I also tried to get to a back-end at that location by going to http://www.site.com/eng/administrator/ (instead of the usual http://www.site.com/administrator/), and indeed, a back-end login screen pops up, only it doesn't accept any credentials.
So, any idea how I can change content on different languages?
