that is intended by design.
static pages and single posts do not have a sidebar;
for static pages, there is a page template with sidebar which you could select under ‘Page Attributes’ – ‘Template’
don’t edit Twenty eleven directly – create a child theme to make the edits there http://codex.wordpress.org/Child_Themes
Thanks for replying,
where do I find the Page Attributes?
dashboard – pages – all pages: then click ‘edit’ below the page name of your choice -> ‘page attributes’ should be on the right on the ‘edit page’ page –
if not, click ‘screen options’ near the top right of that page and tick the ‘page attributes’ tick box.
Perfect!
Thank you so much.
How about using a background image for the menu bar?
