Payment in Euros doesn't process order anymore.

Since I ship worldwide, people sometimes send me money in euros.

Ever since I started my website, overseas transactions were working perfectly. The payment would automatically be converted into USD by PayPal.

Now, whenever overseas customers checkout via PayPal, I have a pending transaction that I have to "accept". Then, no order information is picked up by zen cart. Someone just sent me 95 euros. I have to "accept" the payment in PayPal and I have no clue what was in their shopping cart.

I have no idea what is causing this, but it is either on Paypal's end or Zen cart's.

Enable the EUR currency in your PayPal account, and it shouldn't hold up the transaction anymore.

Chances are the reason the details aren't added to your store is because the currency amount can't be matched up due to exchange rate differences, so when ZC tries to validate the IPN coming from PayPal it won't validate and thus is ignored. Using Express Checkout instead of Payments-Standard would prevent that problem.
