We're still experiencing this issue with customers who are choosing Paypal payment at Check-out, Customer is re-directed to Paypal's Server page to make their payment, and may get "important Order Was Cancelled By Customer" after returning to our store.
Customer writes: "I finished my transaction on the Paypal page, and it just kept loading at the part where it was about to redirect me back to your site. So, I force refreshed the page and when I got back to your site it said my order was cancelled."
I can replicate issue logged as Customer, but it's not consistent. The Paypal Processing page Circle either keeps spinning, forcing a refresh to page, triggering "important Order Was Cancelled By Customer" after returning to our store. OR everything works fine, and Paypal processing page directs you back to our store with "Order Placed.
URL for "important Order Was Cancelled By Customer" page
OR it works fine

*I did do support tickets with both CS-CART & Paypal. Both parties said everything is OK.
*This issue pushed me to using Paypal Pro 3 weeks ago. It allows on-page check out for credit cards. We haven't experienced any issues with this payment option yet, but would to keep offering customer both options.
Update for those following this thread.
CS-CART Tech Support installed patch for me on Thursday (3/30/17) to fix this issue and everything has been working fine until this morning, and the issue occurred again.
Customer: "I waited for Paypal to re-direct me back to your store"
Is that where the issue lies? Error only occurs if customer doesn't click re-direct link back to our store?
I will update Tech Support with this infomration
I switched to Paypal Express to see if that makes a difference. I will update everyone by this friday about my results.
Hey everyone, sorry for late reply, but just wanted you to know it's been 10 days without any issues, after switching from Paypal standard to paypal Express!
