[FreePBX 2.11beta2] Interface language not changing

Hello.

I have FreePBX 2.11beta2 and Asterisk 11 on Ubuntu 12.04. All works correctly (i think), but when I try to change interface language (by clicking to a ‘Language’ button in right top corner), nothing happens. Page reloading, but language don’t change. Log files are clear. Where is my mistake? :slight_smile:

FreePBX and Asterisk was installed via this manual: http://highsecurity.blogspot.ru/2012/12/quick-and-dirty-asterisk-11-and-freepbx.html, which generally identical manual from freepbx wiki.
