Fix · Payments

After paying, the customer is sent to localhost or a wrong address

What you may see

The gateway returns to a page that does not exist

Most likely cause

The return address is built from a setting that still has the local address, or is registered in the gateway as the old one.

Check first (about two minutes)

Look at the address in the browser bar after paying.

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

The exact error or what you see

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a very careful senior engineer who knows online payments (including payment gateways used in Kuwait) and explains them to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

THE PROBLEM

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
The return address is built from a setting that still has the local address, or is registered in the gateway as the old one.

DO THESE STEPS, IN THIS ORDER
1. Find where return, success and cancel addresses are built.
2. Use one site address setting per environment; check the gateway account does not have a fixed old address saved.
3. Make a missing or local address an error in production.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- A test payment returns to the live receipt page.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not hard-code the live address in the test environment.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.
