A couple other thoughts
I've had conflicting info from these forums -- this could be the problem.
For PayPal Express, one forum answer was to use PayPal's API user name, API password and API signature.
But your help in the wizard says to use your paypal email address, paypal password, and API signature.
Which is it?
I've used both methods and get the same failure.
If I change these setting on the confirm.php and pp_confirm.php pages,where else might I need to change them? Is it necessary to upload the entire ecart and security assist folders (I have been, but do I need to?).
Is it necessary to have my SSL already installed?
Help. I'm sooooo close. Thanks.
