UBB.Developers Forums UBB.threads 7 Development How Do I? Subscriptions

I'm assuming that subscriptions is the .threads answer to the .classic practice of sending all posts to a user (like moderators).

If this is the case - I've turned subscriptions on and have set up a cron job. However, I'm getting this error
[] subscriptions.php: cannot open ?: no such file
[/]

I've changed permissions to 777 for this testing and made user my paths are correct.

I noticed that in the subscriptions.php the following lines of code require a path.

// Require the library
require ("/home/www/html/ubbthreads/main.inc.php");
require ("$thispath/languages/${$config['cookieprefix']."w3t_language"}/subscriptions.php");
$html = new html;
$mailer = new mailer;

since my path is not /home/www/..... i changed the path statement to read thus:

// Require the library
require ("/usr/local/www/vhosts/livehope/threads/main.inc.php");
require ("$thispath/languages/${$config['cookieprefix']."w3t_language"}/subscriptions.php");
$html = new html;
$mailer = new mailer;

and it still doesn't work.

Can anyone tell me what I'm doing wrong? Or perhaps there is another piece of code I must alter?

Thanks.
