Authorized.Net declines credit card payments?

[guest_user]

My e-junkie checkout page has some problems that I can't figure out. The payment processor always decline credit card payments. I've tried many credit cards and all of them were declined. Can you tell me why? Is it my payment gateway's issue or e-junkie setting? I use Authorized.Net as my payment gateway.

That's something that is completely controlled by Authorize.Net, so you will need to contact them.
