 * I am not sure when this error popped up, may have been after the latest auto 
   update from WordPress. I am seeing this in below Simple Author Box.
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘
   wps_theme_author_box’ not found or invalid function name in /home/account/public_html/
   wp-includes/class-wp-hook.php on line 298
 * I see this when debug = true.
 * Is there a fix for this?
