I want to implement paypal IPN at my website for that purpose I created 2 paypal sandbox account of type business (seller) and personal (seller) through my paypal developer account. Thereafter I created buy now button at my paypal sanbox business account with item name, code, price etc... and generated a code for buy now button, pasted it on my website. For first few day i.e 14-15 dayts testing work smoothly thereafter it started giving errors like "Sorry we cannot complete your purchase at this time. Please return to the merchant and choose other way to pay" Hence again I created 2 seperate sandbox accounts, again same problem happened after 2 weeks. Kindly help me, what should be main reason behind this type of errors and how to rectify it. Thanking you.
