Recently, I updated my site to PHP7 (had to update the PHP to keep up with TLS requirements PayPal needs), and my whole site fit well on the new server settings, everything except DLguard.
If not familiar with it, DLguard is something that, after someone orders, sends them a link via email, where they can download the ebook.
However, my developers said it was "breaking the site" if you will.
I was wondering if:
1) have you come across any similar problems, or are you familiar with dlguard, and if so, what do you think may be preventing it from working
2) are there any other automatic download programs like this?
