private-messages-for-wordpress

Wasn't getting email notifications when a message was sent to inbox. Found in send-page.php (plugins/pm4wp/inc/send-page.php) the following code... $recipient_email = $wpdb->get_var( "SELECT user_email from $wpdb->users WHERE display_name = '$rec'" ); ...on line 120 needed to be changed with... $recipient_email = $wpdb->get_var( "SELECT user_email from $wpdb->users WHERE user_login = '$rec'" ); ...as it was trying to pull with username, not display name. Hope this helps anyone running into the same issue.
