I am integrating my website with paypal payments. Everything is working fine in sandbox url. Even the payment is also done in sandbox. But when i change sandbox url to live url the site is asking for login details for payment but payment is not happening. Its showing return to merchant page. The payment is not happening in live url. Please help me solving this. Its very urgent. Also in sandbox auto return to success page is not happening. Though i had enabled the auto return in merchant account and also the return url.
