I have followed all instructions for the pay pal integration, but all orders remain payment_processing after a succesfull paypal payment.
I can see the postback being done in the paypal website, so it looks like magento is just not processing this postback correctly.
Tried fixes posted on http://sergiy.kyrylkov.name/blog/2010/05/payment-problems-in-magento-paypal-standard-with-ipn-after-upgrade-from-1-3-x-to-1-4-0-1/ with no result.
Also tried to replace the paypal module in the core with version 1.4.2 since I can see some changes in the files.. this had no result either.
Please help, since I now have manually change the status of the payment in the database to get goods shipped by our fullfilment company.
Also entered it as a bug as I couldn’t find any open cases like mine: http://www.magentocommerce.com/bug-tracking/issue?issue=10549
