Credit card field is missing on checkout

[Frontiers]

Hi folks -

I'm having an issue with with taking orders - A customer wrote the following to us.
"Here is the screen shot from my computer. I have tried using netscape,
firefox and Internet explorer. The problem is that it will not let me
choose what type of CC I have. So, when I put my credit card number in
and your system tries to authorize it, it can't. It says the credit card"
is the wrong type."

I logged into the system as a customer in different ways and the credit card
field was missing - you couldn't choose between Visa, Mastercard, etc. I use
Linkpoint which is the only installed Payment Module. This wasn't a problem as
of yesterday.

Any ideas what could have caused this? I looked at all the settings and they
seem correct, and I don't believe anything's been changed. I'm attaching
a piece of the screenshot with the customer's information edited out. I put an
red oval around where the credit card field would normally be.

Thanks for any assistance, and God bless,


Sebastian

zen cart dosnt need this dropdown,
look in your admin -> configuration -> credit cards and make sure that you have turned ON all the card types

also make sure that the account at linkpoint is setup correct,

Visa and MC shouldnt be an issue but make sure that your discover and amex merchant account numbers are in place and active
