Database table error

Hi,

The file manage.php in line 64 has the next query:

$query = "SELECT b.* FROM ".$wpdb->prefix."wpr_followup_subscriptions a, wpr_post_series b where type='postseries' and sid='$sid' and b.id=a.eid;";

This query call a db table named wpr_post_series, but it doesn’t exist.

What is that? The table is not nedded?
