“About this blog” area reserved in sidebar not showing up

I am using the Ecolution Warrior theme, by ThemeWarrrior. There is an area on their demo ( https://demo.themewarrior.com/wordpress/index.php?wptheme=ecolution-warrior ) where on the sidebar it has an “about this blog” section.

In the themes sidebar.php there is an area that is specified “you can use this part to write about your blog, and even post a picture of yourself.” Anything I put there does not show up. I am not sure what to do. Can anyone help me? Here is the small snippet of code from the sidebar.php. If you need anything else, just ask. Thank you.

<?php if ( !function_exists(‘dynamic_sidebar’)
|| !dynamic_sidebar() ) : ?>

<div class=”rightcol-block clearfix”>
<h2 class=”section-title”>About This Blog</h2>
This is the place where you can write a short description about your self and your blog, you can even put a photo of your self.
