Hi maggieymae!

It depends on which Theme you are using but you can try to go to Pages and see if you can change the template for the page. You do this by :
Go to Pages and select Edit for a already saved page or add a new if you havent created one yet, Then to the right side under Page Attributes go under Template and see if you can change to a template without a sidebar.

Hope this helps Magnus

You could try to put this in the css styles.

.slides:after {
content:none;
}
