In index.php, changing the line:
$countposts=$DB_site->query_first('SELECT COUNT(*) AS posts FROM post');

to:

$countposts=$DB_site->query_first('SELECT postid AS posts FROM post ORDER BY postid DESC LIMIT 1' );

and line:
$countthreads=$DB_site->query_first('SELECT COUNT(*) AS threads FROM thread');

to:

$countthreads=$DB_site->query_first('SELECT threadid AS threads FROM thread ORDER BY threadid DESC LIMIT 1');

should do the trick!

Enjoy! \\=^))
