Payment gateway isn't setup to test orders. This store can't accept real orders or real payments.
This is the error I have, I have had orders so far but this is the first time I experience this error.
Please let me know what to do.
If your store is not in development, feel free to post a new topic here with the details of what you're experiencing, including which payment gateways are involved and whether any error messages are coming up. Thank you!
