Hello everyone, guys, how can I find a piece of code if it is not in the files, but Google shows that it is?
The bottom line is what I found so it should look in the original ->

and how to find and fix classes xs!
All files prosharil not where there is no such!

In the language files:
catalog/language/en-gb/en-gb.php
catalog/language/ru-ru/ru-ru.php
find the line

$_['text_home']             = '<i class="fa fa-home"></i>';

and change the class there.
