Sidebar keeps changing from "right sidebar" to "blog sidebar"

Hi all,

I have created an “about us” page and set the layout to include a sidebar – set to right sidebar. I’ve customised this is the widget area to include a couple of videos – am using the “video sidebar” plug in as the regular video widget I can’t seem to fathom, it doesn’t display no matter how I enter the youtube link.

This displays fine for a while on the live site, then resets to the default blog sidebar. Is there an obvious reason why?

I’m using Shotzz theme from WP Titans.

Thanks!
