Hi Mike, copying and pasting the URL in the browser won’t record the click because that is not considered as a click. For a click to be valid I make sure that the visitor followed the link from a web page or email or something so this reference can be recorded in the database too. If you paste the address directly in the browser then this does not satisfy the definition of referral. This can be easily changed if you want on your installation though.
The double click record issue is related to how different browser handles redirection (on IE you won’t see this behavior). At the moment the Affiliate Platform plugin doesn’t do Unique referrals (this is something I will add in a future release) so it doesn’t really hurt to have multiple clicks.
I tried to keep it as simple as possible, so all I have tried to make sure is that the very core functionality of an affiliate software works (an affiliate sends traffic your way and he/she gets proper commission for that referral).
