I didn't receive any order records in admin after paying with paypal standard in live mode. However, when i test in sandbox, everything is fine and i can receive orders on the admin end. When i try to configure IPN on paypal for live mode, it was realised that the transaction details keep retrying and can't get to the admin side even though the return URL is accurate. I am totally noob in coding and programming and would appreciate if someone can teach me how to solve this. Thanks in advance.
