Ok, I have found the reason for my problem.

It's because I have phpadsnew running on my forum (banner management software)

I have this code in phpinclude_start

require ('/usr/local/apache2/htdocs/phpads/phpadsnew.inc.php');
if (!isset($phpAds_context)) $phpAds_context = array();
$phpAds_raw = view_raw ('zone:1', 0, '', '', '0', $phpAds_context);
$bann = $phpAds_raw['html'];

And then somewhere in postbit there's is that $bann where a banner should be showing.

If I remove that code Arcade works beautifully!

Now the question is... how to get those two to work together...
