Empty Space in Sidebar

This is controlled by your theme. What theme are you using? Where did you download it from?

You are using two different CSS classes for these two pages. https://bit.ly/1wwOcpd is using

.main.sidebar-left {
background: url(img/sidebar-left.png) repeat-y left 0;
padding-left: 340px;
}

The main home page, https://disneyexaminer.com/ , is using this

.main.sidebar-left .sidebar {
float: left;
margin-left: -340px;
}

You will notice on the home page the you are using sidebar and sidebar-content tags in your html/php and on the other page you are using the main group sidebar-left tag in your html/php.

You are going to have to make some coding changes in the template page that renders the code that builds the page with the large space to use the same tags as the home page.

I hope this helps.
