Just because something's working before the upgrade doesn't mean it's going to continue to do so afterwards.They still blame you or your server even though before their upgrade it was working 100% so the issue has to be the upgrade
I've been working with WHMCS software since '06, and in that time have run across only one upgrade issue, and that was my own fault.
In the time I spent working with WHMCS support, same thing. In almost every single occasion, the upgrade issues were caused by the user's install. Either not meeting the system requirements (which do change), having out of date templates, modules or hooks causing problems. Very rarely was the issue caused by the software itself. That's not saying it never was, but the odds are that it's not the software
