XF 1.1 Google Plus button doesn't work after upgrading to 1.1.4

Hello, all!

I have updated my Xenforo to 1.1.4 and my Google Plus Button doesn't work any more.
I tried to set microdata to false for breadcrumb, even remove breadcrumb at all (solution from http://xenforo.com/community/threads/google-google-1-button-issues.17803). No results. Also I tried to load Google Plus One via script in <head>, but without any results too.


When I click on G+ button (in Share This Page block), it loads G+ popup, but after that popup is hidden and js error is thrown in console. And G+ functionality doesn't work.

Can you help me, please?
I resolved this issue. It happens because header param 'HTTP_ACCEPT_LANGUAGE' (library/MausXFR/LanguageSwitch.php) is required in Xenforo 1.1.4.
