Originally, this part:
does not exist in our theme. You probably modified the theme files or this part is included by a plugin that you installed after initial theme installation.
You can hide this area through css by adding this to style.css:
Code:
div#sidebar { display: none; }
Anyway it’s better to find and deactivate the plugin that creates this mess.
Also, you should add this in style.css:
Code:
nav.woocommerce-pagination { clear: both; }
ul.page-numbers li { display: inline-block; }
