UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support 5.4.4 - $sth is not an object

Recieve this message when viewing viewmessages.php:

Warning: $sth is not an object in /home/sweetle/public_html/wwwthreads/viewmessages.php on line 160

Here's viewmessage section:

// ----------------
// send the footer
$sth -> finish;
$html -> send_footer();

Any ideas what's happening here and how to fix it?

Go ahead and try pulling out that $sth -> finish; line
