Old thread, I know.... but has anyone updated the above hooks to work with WHMCS v8.x? The whmcsjet hook to disable 0.00 invoices stopped working after upgrading to WHMCS v8.x.
WHMCS support has been wonderful in helping resolve this, but I'm sure others are having the same problem. For other HostGator resellers that use WHMCS, I've documented how to easily fix the dreaded connection error in the HostGator environment here:

@EduardoP737, would you be willing to share (or in a Private Message) who your hosting provider is? I'm going around and around with mine on this same issue.
