Fair warning: I know almost nothing about websites. Consider me 100% ignorant. I have created a new Authorize.net Login Username and Transaction Key to be used for our credit card processing through our bank. I am having trouble with the shopping cart, which is not allowing me to save edits made to the payment modules. What I have done: Go to osCommerce website, where the shopping cart is hosted. Go to Administration > Modules > Payment. Select Authorize.net module. Click “Edit”. Enter new Authorize.net code and new transaction key provided by Authorize.net. Click “Update”. But after clicking “Update,” I am taken back to the modules and the new numbers do not show, the old numbers show. How do I get the new transaction key to “stick”? Shouldn't it be showing me the new key after I click "Update"?
