Question

I'm trying to ask a question and in the Essence of the question I write the following: "How to make a directory in Nginx that will take data from another server?" But the warning is lit "According to the rules of the Russian language, the title (and each new sentence) begins with a capital letter?" What is the error of the loser in the Russian language ???

Answer 1

Write in Russian! Your first letter in a sentence is: K - latin

Answer 2

Comma before 'which', from another server.

Answer 3

Make sure you don't put a space before "How".
PS Did you type this from a computer or from a mobile device?

This is Toaster's error.
