Payment not possible

I am getting error messages on several credit cards and even if I am click on the paypal link

Your transaction could not be completed. There is a problem with the credit card or billing information you have entered.
Please, return to the checkout page and try again.

Is this happening on checkout from our site?

if so, contact the sales department by phone:
888.490.1545 toll free in the U.S.
1.858.768.6600 international

Monday-Friday, 9am - 5pm PST

and we can go through the transaction with you to see what is happening.

Changed a template into a theme and the results are blank pages. I am using DW CC 2014

a blank page means that a php error is occurring but error reporting is turned off.

to turn error reporting on, add the following code at line 1:

<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>

once we know what the error is, we will be able to troubleshoot the cause.
