Project description:
"My checkout page freezes whenever a customer tries to complete a purchase with a credit or debit card—the payment gateway simply stops responding. All other steps on the site work, and alternative methods such as PayPal or bank transfer process without a hitch, so the problem is isolated to the card-processing flow.

I need the underlying cause identified and resolved. That could involve digging into gateway logs, updating API credentials, patching any JavaScript that blocks the request, or adjusting server-side configurations so the gateway’s callback comes through reliably. Once the patch is in place, I also want to see at least two successful live test orders and a clear note of what was changed so I can maintain the fix moving forward.

Deliverables:
• Diagnose and eliminate the “gateway not responding” error for credit/debit card payments
• End-to-end test confirming normal order completion and order record creation
• Brief, plain-language summary of the root cause and the exact steps taken to correct it

If you have experience with payment SDKs, webhook debugging, and checkout flow optimisation, this should be a straightforward task." (client-provided description)
