I am using Twenty Eleven theme. When I view an archived post from a link within my website, the post shows the sidebar.
When I use an outside link (for example a link to my post from Facebook) the post does not show a sidebar.
What do I need to do to make sure a sidebar is ALWAYS showing?
Bear in mind, I am NEW to WordPress so the simpler explanation, the better please.
