Кто нибудь сталкивался с такой проблемой?
I have to admit, that I am not able to understand your error message, as this one doesn´t get translated as well.
So far, I can only kindly invite Pavel Homeriki to this. Or you could translate your error message into English, please.
Error 500 usually means there's a problem generating code for web fonts. Are you using Typekit fonts?
See htis link.
