Hi, I have the same issue. Simply, when I do a test account I need whmcs to connect with whm and make a cpanel and collect the url / username / password and send it to the new user. (after order acceptance)
In the module tab I have added the package name with user first and added the user and pass for whm and selected make cpanel on sign up but I just do not seem to get that email which confirms the system has set it up correctly.
Any ideas at all? I have paid for a whmcs configuration and stipulated this clearly, but it hasnt been done. I have tested it 3 times and only get the whmcs system emails, but no email giving the cpanel details. This is such a simple fundamental requirement, surely its not so hard!
