I now remember this problem. I posted a fix for this 3 years ago. Unfortunately this mod is so badly supported, in spite of the fact that it is ported to version 3.0, the fix was never implemented.

It's the downloads.php addon which has some false xml statements.
A correct vbseo_sm_downloads.php (for rsjelle's downloads II mod) should read this (marked the changes in red):

	if(!defined('VBSEO_SMDIR'))exit;
	$mods = $db->query
("SELECT id,name FROM " . TABLE_PREFIX . "dl_cats ORDER BY `id`");
	while ($mod = $db->fetch_array($mods))
	{ 
		$url = $vbseo_vars['bburl'].'/downloads.php?do=cat&id='.$mod['id'];
	if(VBSEO_ON)
		$url = vbseo_any_url($url);
		vbseo_add_url($url, 1.0, '', 'daily');
	}
	$mods = $db->query("SELECT id as fid FROM " . TABLE_PREFIX . "dl_files");
	while ($mod = $db->fetch_array($mods))
	{ 
		$url = $vbseo_vars['bburl'].'/downloads.php?do=file&id='.$mod['fid'];
		if(VBSEO_ON)
			$url = vbseo_any_url($url);
			vbseo_add_url($url, 1.0, '', 'daily');
	}
?>

Again... same problem after 3 years. I hope vbSeo will correct this some time.
