Fatal error: Call to undefined function generate_page_rewrite_rules()

I added feedburner links (settings:feedburner) because they were empty. Then I got the error: Fatal error: Call to undefined function generate_page_rewrite_rules() in /home2/strength/public_html/blog/wp-content/plugins/ol_feedburner.php on line 43

I found the text but have no idea what to do now. I cannot see the feedburner links to correct the feeds.
Here’s the text it calls for:
}

function ol_feedburner_options_subpanel() {
global $ol_flash, $feedburner_settings, $_POST, $wp_rewrite;
if ($feedburner_settings[‘fixed_htaccess’] == false) {
generate_page_rewrite_rules();
save_mod_rewrite_rules();
$feedburner_settings[‘fixed_htaccess’] = true;
update_option(‘feedburner_settings’,$feedburner_settings);
}
