Hey there armandojr423,
How are you doing today?
This should be possible with some custom CSS. Could you please try adding the following CSS code in the style.css file of your child theme or if your theme doesn’t have custom CSS tab add it in your site using the following plugin:
http://ww.wp.xz.cn/plugins/simple-custom-css
#secondary.widget-area {
display: none;
}
#primary.content-side-area {
width: 100%;
}
This should remove the sidebar and add 100% width to content area. If this doesn’t work could you please post link to your page where you want this removed so I can take a look?
Best regards,
Bojan
