Help! My checkout page doesn't appear to work.
It doesn't matter which Payment Gateway is selected, as soon as the user logs in/completes registration, and attempts to pay, the page simply comes up blank.
It does not redirect to Paypal, and I'm not sure where it's supposed to redirect Mail In Payments to, but it ain't doing that either.
Can anyone advise any files that could be the culprit? And how it could be made to work?
I have checked all my config settings but I can't see anything that relates to this issue.
Also I note that when a customer attempts to order a Product Addon, the only available gateway is Paypal. Why isn't Mail In Payment listed? Again, I have checked all my config but see nothing that would help.
Thanks in advance folks!
