I disagree with this patch, and funny, this was caught by me almost 8 months ago, in orca 1.2 - if you add this patch, it allows certain tags to be included in the title text, this is a problem, who wants an image or what not as a title - try it :) - this is the correct fix, without changing forum.php - in utils.inc.php - change:
function prepare_to_db(&$s, $iAllowHTML = 1)
{
if ($iAllowHTML){ cleanPost($s);
}
to:
function prepare_to_db(&$s, $iAllowHTML = 1)
{
if ($iAllowHTML){cleanPost($s);}else{strip_tags($s);}
}

This see more fix will strip ALL html out of the title --- much nicer...

:)

I posted this somewhere a WHILE ago...
