Andrew H Posted April 4, 2015 Share Posted April 4, 2015 I have an online shop that has been upgraded through various versions through to version 1.5 Orders don't validate, so whether I use bank wire or check/cheque option the page hangs. If I use paypal, the order doesn't appear in the back office and PayPal IPN history registers a 500 error -although it does usually succeed in posting on the second attempt (but the order still doesn't appear). If it try and manually create an order from a cart, I get a 500 error. I've tried creating a fresh test product and I get the same trouble as I thought it might be some problem with a product from the old database Although I do plan to upgrade to 1.6, it's not something I want to go through right now so would prefer to getting it working in 1.5 rather than start again. I do remember some known problem like this related to upgraded shops although not sure of the cause or possible resolution. Any ideas? thanks Link to comment Share on other sites More sharing options...
melriks Posted April 14, 2015 Share Posted April 14, 2015 I have this trouble too. I suspect it has to do with the PayPal IPN not returning properly to Prestashop, but I can't find any solid information about whether IPN is needed with the new PayPal USA module.

bellini13 Posted April 14, 2015 Share Posted April 14, 2015 IPN is required for PaypalUSA, it will not work otherwise. However there is nothing you need to do special, the module tells Paypal what to do with respect to IPN. If you are not getting orders in the back office, it will be one of 2 things 1) You are not receiving the IPN. For this, you need to review your access log and determine if they are infact being received. If they are not, then you should contact Paypal support directly and let them know it is not being received 2) You are receiving the IPN (confirmed in the access log). In this case, the IPN processing is failing. There is no easy fix for this. It will require testing and code tracing to determine where in the IPN process it is failing. You are likely going to need to hire a developer to troubleshoot this. In my opinion, if you are going to pay a developer to fix Prestashops module (that they can't be bothered to release a new version with fixes in the past 9 months), then I would suggest you instead use that money to buy a working and supported Paypal module.

RamboRich Posted April 5, 2016 Share Posted April 5, 2016 Just an FYI - I was having problems with orders not showing and after a few days researching i've finally found a solution (at least for me). Sales tax was being charge in Paypal for shipping costs, which wasn't jiving with what the Prestashop amount was, therefore, no order confirmation or record of order in backoffice even though the amount was still being withdrawn from customers account and residing in PayPal. Find it in this thread: https://www.prestashop.com/forums/topic/328666-how-to-fix-paypal-usa-133-prestashop-1606-getting-404s-not-fulfilling-orders-on-return/ Link to comment Share on other sites More sharing options...
