You left out the two lines that precede these lines, so not sure if you are using XBT tracker...but I assume not.
Anyway, instead of adding the url to the empty announce...add /announce.php to the current one.
Should read...
Code:
} else {
$INSTALLER09['announce_urls'] = array();
$INSTALLER09['announce_urls'][] = 'vikingbits.org/announce.php';
$INSTALLER09['announce_urls'][] = '';
Also, I tried registering on your site, never got the confirm email, my account not activated. Tried recovering account, but system said could not send email.
