multilingual problem

Hello everyone

I use Ecalypse pluging well. I have a problem to changing language. I use Polylang multilingual plugin, when I change the site language, Ecalypse wont change. How can I connect between Ecalypse and system language?

By the way, I couldnt show Ecalypse language switcher. I wrote html code to show, but I saw nothing.

Thanks for your good pluging. I hope You will help me to fix this issue.
