Update to StupidGenius
My most appreciated WordPress theme, StupidGenius, has been updated just now (again). By default, in single posts and pages you have no sidebar. Most users like that, because of its clean look and good readability of post’s content. Some of them prefer the sidebar to be always displayed, instead.
With this update you can simply delete single.php and/or page.php files from the theme’s folder to have your sidebar back in place.
