On Twenty Eleven or on its child themes the default template for new pages is a template with no sidebar. I don’t know why this is like this; it seems to me that the designers of WordPress are still not thinking about CMS functionality in some places.
For example the most obvious place to put a menu in a CMS is the sidebar. But with Twenty Eleven the only way to show a menu in all pages is to explicitly set all the pages to “sidebar template”. I would think it’s a design bug, as the only solution so far is to tell everyone to “don’t forget to set the new pages to “sidebar template””.
I’m sure there must be a single line in functions.php which changes the default action but I don’t know what that line is. Could you tell me what should I write in functions.php to set all new pages to “sidebar template” when using Twenty Eleven?
I’m sure that it has been asked before but I really couldn’t find it anywhere using the search function.
