I've set up and additional domain for http://sequencebreak.ru — http://sqncbrk.com according to the instructions from the docs http://learn.getgrav.org/content/multi-language#setup-with-language-specific-domains
It seems to work for the most part — translations from the languages.yaml are loaded. But somehow override templates which I've placed in the /templates/en folder don't work unless you specifically set the language with the suffix. Check the http://sqncbrk.com/en. The only difference is the date format actually, but I couldn't come up with any other idea than having a language-specific partial.
