Hello,

i have the same problem when return from paypal after payment with success.
i receive this message :

error [PP-1102]: Sorry, this order has already been processed or does not exist

my order is not saved in Backoffice and no sending summary email

(note: before returning to the main site, i’m invited to resubmit the page ! is it normal ?)

Here’s my Paypal log file (with pending status !) :
