I am testing my store's credit card payment module with a test account (module is Transaction Central). When I use a fake credit card (4111111111111111) I get the following error at the top of the page: There has been an error processing your credit card. Please try again.15/No such issuer.
Is this normal? If I test with a real credit card and charge a penny, I don't get the error. I am not live yet; still using a test account.
I am on Zen Cart 1.38a, and the store is hardly customized at all. I have changed a few side boxes and some of the pictures and labels according to the FAQ/ Tutorials online. I looked for this error message in the FAQs and tried to search the forums but could not find an answer. Thank you.
