Since upgrading to 4.11.2, Users are getting a 404 error page if they click on "cancel and return" instead of returning to the checkout page.
I'm almost positive this is a SEO issue, but I can't seem to nail it down specifically. I've looked in the DB and addon folders and I don't see anything different or out of place. I've also installed a fresh store which does work as expected and compared files, again I don't notice anything out of place.
Permissions in the paypal addon is 755, 644...
This is the return URL:
index.php?dispatch=payment_notification.cancel&payment=paypal&order_id=11111
Which should redirect back to checkout.
Anyone have any suggestions on what to look for? Maybe I'm overlooking the simplest thing.
