Orders not processing

[AMI]

I have a fresh install of Zen Cart's newest release.

When an order is placed either using PayPal or Credit Card as payment option, it goes through all the motions of processing an order, but it fails to actually charge the PayPal account, or the credit card.

It sends a confirmation order number, but we wait and wait and wait, but no charge shows up.

Any ideas what I've missed in my set up?

This issue is still unresolved. Does anyone know what could be the problem? It's a brand new install. I activated PayPal and Credit Cards for the payment options. I set up the PayPal requirements.

Yet the charges don't show up in PayPal or on a credit card if someone places an order.

Thanks for any help.
