Pues yo veo que no estas cerrando la llave de function
wp_get_db_schema Código PHP:
function wp_get_db_schema( $scope = 'all', $blog_id = null ) {
global $wpdb;
$charset_collate = '';
if ( ! empty($wpdb->charset) )
$charset_collate = "DEFAULT CHARACTER SET $wpdb->charset";
if ( ! empty($wpdb->collate) )
$charset_collate .= " COLLATE $wpdb->collate";
if ( $blog_id && $blog_id != $wpdb->blogid )
$old_blog_id = $wpdb->set_blog_id( $blog_id );
// Engage multisite if in the middle of turning it on from network.php.
$is_multisite = is_multisite() || ( defined( 'WP_INSTALLING_NETWORK' ) && WP_INSTALLING_NETWORK );
}
