I changed from a theme I had previously that used a plugin called simple page sidebars. I have already deactivated plugin this just in case it was the problem, but for some reason I cannot get my widgets to show up in my sidebars.
While opening your site i could not find any thing. Its under maintenance. If you got a problem then we cant help about the plugin problem. We just help to you about our theme. We have our theme and with side bar too. And that must work. Install your fresh theme and have a look there. The sidebar must work.
