Is v3manual.whmcs.com the current manual?
This manual is missing a lot... Conceptually there are no explanations of what any of the screens do in the admin control panel...
Like what is the difference between a "reseller" account and a "shared hosting" account? Does this only apply if you are using cpanel hosting? If I am on Plesk, what would a 'reseller" account do?
I am running some tests on the system using Plesk servers. Whenever I simulate a returning user who orders another hosting account, WHMCS seems to try to create a new account on the same server using the same client ID, so the order fails every time. How do I get around this? How does a returning user create a new hosting account without colliding with his existing username?
