UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support Lost subscription emails after installing 6.5.2

Hi,

Windows 2003 server, IIS installation
I trigger the cron/php/subscription.php page every 4 hours via the scheduler service in Windows. Worked like a charm before installing the 6.5.2 update (from previous 6.5.1).

I did check the subscription.php for obvious errors and also called it manually via a browser. No emails are sent. Password emails and emails sent directly to users work.

What else can I check?

Thanks
