Archive link takes me to a page without a sidebar

I modified the theme Zenon lite to have a blog page and it has a left sidebar with an archive widget. When I click on an archive or tag link I get direct to a page without a side bar. I want the same left sidebar to be on all my archive pages etc. Is this possible?
