Can we see your site?

Yes.Having a look at your site will allow us to assist you in a much better way:)

We don't need to see your site.

But we do need to know what your currency settings are under Admin->Localization->Currencies
Specifically, what is your exchange rate set to for EUR ?

I believe I have the same problem. I have the same "could not find matched txn_id" error message in my log files, and while my transactions typically work just fine, I just received a paypal payment for an order, but the order wasn't moved from shopping cart into an actual order record.

My site is sales.funforchange.org. I only have one payment module open - PPE. I don't have a currencies option under localization. I've been testing successfully through both sandbox and live.

Another anomoly, whether relevant or not, emails from paypal typically have a subject line "Notification of payment received", but the order that failed had a paypal email "Notification of Payment Received" (different capitalization).

Any ideas of where I should look next or what the problem could be?

Thanks,
Carl
