 * I am running into a “Call to undefined function” error when I try to instantiate
   two sidebars on my site.
 * the following code is my registration of both sidebars in my functions.php:
 * if ( function_exists(‘register_sidebar’) ) {
    register_sidebar(array( ‘name’ 
   => ‘main_sidebar’, ‘before_widget’ => ‘<div id=”%1$s” class=”widget %2$s”>’, ‘
   after_widget’ => ‘</div>’, ‘before_title’ => ‘<h2>’, ‘after_title’ => ‘</h2>’));
   register_sidebar(array( ‘name’ => ‘home_sidebar’, ‘before_widget’ => ‘<div id
   =”%1$s” class=”widget %2$s”>’, ‘after_widget’ => ‘</div>’, ‘before_title’ => ‘
   <h2>’, ‘after_title’ => ‘</h2>’ ));
 * I also have two corresponding PHP files with the following code (tailored to 
   each file):
 * <?php if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(‘main_sidebar’)):?
   >
    <?php endif; ?>
 * Does anyone know why I am getting the fatal call to undefined function message?
 * Thanks,
    Chris

 * `get_main_sidebar()` is not a default WordPress function – if you or your theme
   has not defined this function somewhere, you’ll get the error message;

 * Okay, easy fix. Just had to specify the specific sidebar in my call
 * <?php get_sidebar(‘main_sidebar’); ?>
 * Thank you for the help!
