# Fetch rss issues…

 * I use the following code to spit out the most 10 most recent posts from a blog
   listed in the directory I run.
 * For some reason the code works in one theme, but not the current theme which 
   I like better.
 * $rss = fetch_rss($url);
    $url = get_post_meta($post->ID, “RSS URL”, true); if(
   is_array($rss->items)) { $items = array_slice($rss->items, 0, 10); echo ‘
    - ‘;
       foreach ($items as $item) { $desc = htmlspecialchars(substr(strip_tags(
      $item[‘description’]),0,300)); echo ‘
    - [‘ . $item[‘title’] . ‘](https://wordpress.org/support/topic/fetch-rss-issues/'. $item['link'] .'?output_format=md)
    - ‘;
       } echo ‘
 * ‘;
    } else { echo ‘<p>No feeds yet. Come back soon!</p>’; }
 * gives me the error:
    Fatal error: Call to undefined function: fetch_rss() in /
   www.bestgreenblogs.com/wp-content/themes/just-lucid/single.php on line 69
 * It works in my other theme, but why would it not work in the current one I use?

 * Does there need to be a “if(function_exists” inserted into the line?
