Hi, We've had our Magento 1.7 site running with PayPal fine for many years now but a few days ago we started to get IPN warning emails. Im not sure why these have started to appear as we havnt changed anything. Ive had a look for possible causes but can rule them out. 1 thread said selling on multiple channels e.g. Magento and ebay could cause this issue as ebay could send an IPN to Magento. Ive checked and we had no sales on ebay around that time so it couldn't have been that. I have inquired with our host about them and to confirm our SSL is all upto date etc and the only thing they mentioned is we could switch to TLS 1.2 if that would make a difference? Finally, do I even need the IPNs? If I turn them off will it mean we have to manually check each payment through PayPal and that it wouldn't automatically change the order status within Magento etc? If so I really dont want t5hese to be turned off so how would I go about correcting the problem? Thanks
