I keep getting this error from the feed:

Invalid xml declaration.
 Line: 2 Character: 3

and my php is:

<?php

//
//$result = mysql_query($query) or die ('Error' . mysql_error());

$news_headlines = mysql_query("SELECT n.*,a.* FROM news AS n LEFT JOIN authors AS a ON a.aid=n.n_author_id ORDER BY n.n_time DESC".(is_numeric($config['headlines']) && $config['headlines']>0 ? " LIMIT {$config['headlines']}" : null));
$items_output    = null;

I'm not good with XML, so I can't help much. spit it out as plain text (rather than XML like I'm assuming you're doing now) and have a look at it. is it proper XML? is anything missing from the stuff you're putting out? anything going wrong or unexpected?

[penagate]

There is no XML version 2.0, only 1.0.

Yeah i fixed that and put 1.0 instead, still got the problem
