Feed not working

<link rel=”alternate” type=”application/rss+xml” title=”RSS Feed” href=”” />

bloginfo() doesn’t seem to be working on my site:

This is taken from the WordPress doc:

By default, WordPress comes with various feeds. They are generated by template tag for bloginfo() for each type of feed and are typically listed in the sidebar and/or footer of most WordPress Themes. They look like this:

URL for RDF/RSS 1.0 feed (http://purl.org/rss/1.0/)
<?php bloginfo(‘rdf_url’); ?>

URL for RSS 0.92 feed (http://www.rssboard.org/rss-0-9-2)
<?php bloginfo(‘rss_url’); ?>

URL for RSS 2.0 feed (http://www.rssboard.org/rss-specification)
<?php bloginfo(‘rss2_url’); ?>

URL for Atom feed (http://www.atomenabled.org/)
<?php bloginfo(‘atom_url’); ?>

URL for comments RSS 2.0 feed
<?php bloginfo(‘comments_rss2_url’); ?>
++

Where should I look to resolve this? I’m currently using the “Subscribe Me” plugin in my sidebar, but none of the links display my feed URL.

Thank you!
