Hello everyone!

I seek for customization Salient theme. I have child theme from latest theme package installed. I have already change header.php, it is ok. Now I try to change the recent-posts-extra-widget.php from /includes/custom-widgets/ folder. I created same folder in my child theme for it and placed template with my changes into it. And nothing has happen.

Anybody help me please. What wrong is in my actions?
