HTTP 406 error on invalid credit card

[stagebrace]

When using the direct payment module, I add a CC number but change the last number to something incorrect (simulating a user error). Add the date and CVV values and submit the form. Every time I get the HTTP 406 - The resource cannot be displayed.

The cause of a 406 error should show in your server error logs.

Yep, What can I do so the program shows a pop up instead of an error page?

It's probably a mod_security thing that's triggering the 406 error due to a somewhat malformed URL ... the error message doesn't have a variable assigned to it.

I gather you're using PayPal Website Payments Pro in this case, since you posted in this section of the forum.

You have a couple options:
edit /includes/modules/payment/paypaldp.php
a) around line 363 you'll see a line like this:

      zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, $error, 'SSL', true, false));

Change it to this:

      zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, 'error=' . $error, 'SSL', true, false));

or b) change it to this:

      zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL', true, false));

The first option will correctly form the URL with the error message. The second skips the error message from the URL altogether, allowing the message to simply happen by the built-in messageStack.

Works great now. Thank you sir.
