Host upgraded to MySQL 4.0.13, now code fails

Ok my host decided to upgrade MySQL, now it seem becasuse of this my code no long works!!

Why will this code not work on MySQL 4.0.13

php Code:

Original - php Code

 
<?php 
$db = mysql_connect("localhost", "Gappa", " "); 
mysql_select_db("Gappa",$db); 
 
 
$query = 'SELECT topic_title, topic_id, FROM_UNIXTIME(topic_time,"%W the %D %M @ %r") AS Topic_Date, post_text, username FROM phpbb_topics RIGHT JOIN phpbb_posts_text ON topic_first_post_id=post_id RIGHT JOIN phpbb_users ON topic_poster=user_id WHERE forum_id=6 ORDER BY topic_time DESC'; 
$result = mysql_query($query, $db) or die ($query .': '.mysql_error()); 
 
 
while($row = mysql_fetch_assoc($result)) 
   { 
echo "<br/><b><FONT FACE=Arial SIZE=-1 COLOR=#6699FF>"; 
echo "$row[topic_title]:</FONT></b><br/>"; 
echo "<FONT FACE=Arail SIZE=-2 COLOR=#999999>posted by: <b>$row[username]</b>"; 
echo " on: "; 
echo "$row[Topic_Date]</FONT><br/><hr><br/>"; 
echo "<FONT FACE=Arail SIZE=-1 COLOR=#FFFFFF> $row[post_text]</FONT>"; 
echo "<br/><br/>";  
echo "<FONT FACE=Arial SIZE=-2>"; 
echo "<a href="http://www.hostultra.com/~Gappa/phpBB2/viewtopic.php?t=$row[topic_id]"><b><FONT COLOR=#6699FF>Read comments</FONT></b></a></FONT>"; 
echo "<br/><br/>";  
} 
 
 
 
?>

Sorry I cant recall the previous version of MySQL that was running, but i did work... and now it doesnt and I just get this as a display on my page once the php/mysql code begins: "SELECT topic_title, topic_id, FROM_UNIXTIME(topic_time,"%W the %D %M @ %r") AS Topic_Date, post_text, username FROM phpbb_topics RIGHT JOIN phpbb_posts_text ON topic_first_post_id=post_id RIGHT JOIN phpbb_users ON topic_poster=user_id WHERE forum_id=6 ORDER BY topic_time DESC"

with the following error: "Cross dependency found in OUTER JOIN. Examine your ON conditions"

Any ideas people?

Maybe some fields get repeated across tables? try with:

$query = 'SELECT topic_title, topic_id, FROM_UNIXTIME(topic_time,"%W the %D %M @ %r") AS Topic_Date, post_text, username FROM phpbb_topics RIGHT JOIN phpbb_posts_text ON phpbb_topics.topic_first_post_id=phpbb_posts_text. post_id RIGHT JOIN phpbb_users ON phpbb_topics.topic_poster=phpbb_users.user_id WHERE forum_id=6 ORDER BY topic_time DESC';
