 * When I edit or create a new sermon I get sent to an error page. It still updates
   and creates the sermon but there is obviously a problem.
 * **This is the error:**
 * Notice: Trying to get property of non-object in /home/lifepoi7/public_html/wp-
   content/plugins/sermon-manager-for-wordpress/includes/types-taxonomies.php on
   line 18
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/lifepoi7/public_html/wp-content/plugins/sermon-manager-for-wordpress/
   includes/types-taxonomies.php:18) in /home/lifepoi7/public_html/wp-includes/pluggable.
   php on line 1195
 * **This is line 18 of the types-taxonomies.php: **
 * $service_type = $term->slug;
 * **This is lines 1192-1198 of pluggable.php: **
 *  if ( !$is_IIS && PHP_SAPI != ‘cgi-fcgi’ )
    status_header($status); // This causes
   problems on IIS and some FastCGI setups
 *  header(“Location: $location”, true, $status);
 *  return true;
    } endif;
