Shop stopped working

Out of the blue, when customers order from our shop, they do not get a confirmation email, and we don't get the order email.

Email addresses are working.

I deleted the code that writes order details to the database quite a while ago (for security reasons), but we still received order emails, and our customers received confirmation emails.

I didn't change the code or the database.

To double-check, I uploaded the pages confirm and checkout pages.

As a result, the page now throws an error (duplicate entry for primary key).

How can I fix this?

Attach a copy of the page that gives the error and I can probably spot where the problem is to fix the error.

Thanks.

Checkout international forwards to the other checkout pages as needed (Germany, Canada, Europe, International).

All of your insert bindings seem wrong on your confirm pages in your "store cart summary" and "store cart details" server behaviors.

You should probably delete that code if you don't need it. To get it working without the error you could just change:
$ConditionalQuery->bindColumn("OrderID", "d", "segufix_OrderID", "WA_DEFAULT");
to:
$ConditionalQuery->bindColumn("OrderID", "d", "". ($_SESSION["segufix_OrderID"]) ."", "WA_DEFAULT");

But you might as well delete that code chunk entirely since it doesn't seem to insert any relevant data.

I don't even see the email code on the page. Maybe you removed the email code when you thought you were removing the database insert code? The database insert code appears to be in place it is just inserting bad data.

I left the order ID as a check to see that the order numbers match the emails that we are getting.

It has been working for years and all of a sudden it doesn't.

I changed the port setting in line 83, which weirdly took care of the error message. The success page takes some time to load, but it still doesn't forward emails to me and the customer. On this page checkout_success_canada.php

I suspect it is an SMTP issue. There is no space to enter a password, but our provider says it needs a password (never did before).

You can update your email settings from the success page. If you click the email settings icon in the UI you can set a username and password. The server name looks wrong too, so confirm that with your email hosting provider as well.

Thank you, Ray, it works now. You are a lifesaver.

I found the setting where to enter the password. A password was never required since I built the shop in 2009. That changed without notice.

I have no idea how the error message played into that (the screenshot I sent you). It was there, and then it wasn't.

You should still probably update the line:
$ConditionalQuery->bindColumn("OrderID", "d", "segufix_OrderID", "WA_DEFAULT");
to:
$ConditionalQuery->bindColumn("OrderID", "d", "". ($_SESSION["segufix_OrderID"]) ."", "WA_DEFAULT");

The error is probably still there but the page redirects before you see it.

Thanks. I made the change. It works.

Hi Ray, I have one more question:

The problem was that our email provider now requires a password and username. The change wasn't announced.

Can I double the email behaviour with different settings? I want to use a second or maybe even a third provider to send a copy of the order to myself. If one provider fails, I still have one or two more providers to fall back on.
