Strange error

[FunnyUser]

I have several computers that keep getting error (Windows 7 64bit, FireFox39-43 and IE11):
TypeError: Property 'undefined' of object # is not a function
at Object.handle (/var/www/viacrypt/src/i18n.js:100:41)

From most computers everything working just fine.

That is certainly an error on the server code, most likely on the multi-language (i18n) side.

Can you tell me what language is your browser in? (Technically I'd like to know the Accept-Language request header if you can figure that out)

Browser language is English, Accept-Language Russian.
