First checks are if Linux then ensure torrents folder is writable ie = chmod 777 - Then once thats done i suggest you use a phpinfo.php file in root - point to it then establish your relative path to torrent folder
Code:
<?php
phpinfo();
?>
^^ Save that as phpinfo.php and upload to root - point to it http:// yoursite / phpinfo.php
then look at say apache environment and you'll see a filepath which ends in phpinfo.php - That will look like
Code:
/home/domainname/public_html/phpinfo.php
so that becomes on bittorrent for fileapth :
Code:
/home/domainname/public_html/torrents
or
Code:
/var/www/httpdocs/phpinfo.php
to
Code:
/var/www/httpdocs/torrents
Once thats done your all set
