I'm building a custom wordpress theme. When I turn on debug, I get this message:
Notice: Theme without sidebar.php is deprecated since version 3.0 with no alternative available. Please include a sidebar.php template in your theme. in /var/www/wp2/wp-includes/functions.php on line 2968
However, I do have sidebar.php in my theme. It's copied and unedited, from wp-includes/theme-compat
What am I doing wrong?
