Sidebar doesn't appear in my home page

My sidebar doesn’t appear in my homepage, I try change new template bu nothing. What I do to solve it?

Just delete or rename front-page.php from theme root folder and you are ready to go.

Front page is designed in a way that there are three extra widgets below the content area to customize front page. But removing front-page.php would make it use the default page template which is page.php

How to put sidebar on my front-page, without problems?

I already told you:

Just delete or rename front-page.php from theme root folder and you are ready to go.

Thank you. But I edit front-page.php and works.
