There was a line in the original Showfalt.php file that seems to have been overlooked. At first I deleted it with the the rest of that section. Then I left it in. No luck either way.
What follows is from the original portion of the Showflat file:
$query = "
SELECT B_Replies,B_Counter,B_Last_Post,B_Subject,B_Rating,B_Rates,B_RealRating
FROM {$config['tbprefix']}Posts
WHERE B_Number = '$current'
";
$sth = $dbh -> do_query($query);
list($checkreplies,$count,$posted,$tsubject,$Rating,$Rates,$stars) = $dbh -> fetch_array($sth);
$length = $checkreplies + 1;
Note the last line. This last line was not mentioned in the instructions for this hack. I'm not sure if it was an oversite or not, but I thought I'de bring it to your attention.
