WP Knowledgebase White Line

I’m creating a client help center for my company website, and liked the FAQ layout offered by Knowledgebase more than other plugins. My problem is a vertical white line running through the right side of my theme footer (which is dark grey) and a white space below the footer that contains what appears to be a page number (“1”). I haven’t seen a forum article about this so I’m hoping for some help. I need to delete this white line and the white sub-footer area that contains the page number.

I’m running the Divi Theme on WP 4.7.5

Any and all help would be greatly appreciated!
