If you are referring this post as current page then you have to pass $post->ID.

<?php

$excluded_ids = ep_get_excluded_ids();

if ( !in_array( $post->ID, $excluded_ids ) )

{

?>

<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>

<?

}
else
{
 the_title();
}

?>

You can use something like

$pages = explode(',', get_option("ep_exclude_pages"));

Solution - 3

You could try using ep_get_excluded_ids function from the plugin:

<?php
$excluded_ids = ep_get_excluded_ids();
if ( !in_array( $PAGE_ID, $excluded_ids ) )
{
?>
<a href="<?php the_permalink() ?>">Title</a>
<?
}
?>
