Domain Migration Error from Dev Site to Live Site

-- HikaShop version -- : 2.4.x

I created a website as a development site on a specific domain that was only intended for temporary usage, once ready it would be migrated to a new domain.

I have successfully migrated and modified the database name as well as configurations so that the new domain works as intended.

However, every time an order is placed the order is sent to the old website and old domain. I am even receiving emails from HikaShop that say:

Hello,
A merchant_name notification was received with the status Accepted. The order is now confirmed.

This notification was for the order on the website example.com/hikadev/
You can access the order details directly by clicking on the link below after logging in your back end:
example.com/hikadev/administrator/index....l=order&task=listing

So even though the live site and the true domain is working to generate orders, the orders are being associated to the old site. Is there any reason you can think of that might cause this?

Note* - I am aware of the out of date version of the component but that shouldn't have anything to do with domain issues.

You are correct. I did not update that variable but that is because that variable was empty to begin with. I have edited the variable to have the new domain just in case but I don't believe that is the cause. Any other ideas?

That all makes sense but I changed the variable value as suggested yesterday but still I received an email this morning with the same problem of the old domain. Is it possible that the site could actually be redirecting to the old dev domain which is why the emails are displaying this issue because it is accurate on the old site and an unintended redirect is happening?

Edit: I figured it out. It was a redirect problem with a leftover override that I hadn't addressed that was in fact causing a redirect. I've solved it now. Thanks for the assistance in narrowing down the issue.
