Hmm... I need to find out myself. I don't know what is the right answer to your question. I'll do some investigation and get back to you if I find an anything. You should email the people at Verisign as they probably know..
I'm also interested in this issue as well....does anybody have any information?..
My OS Commerce is doing the same thing. The last order that came through correctly was paid by check, then the 2 paypal orders didn't come through... Could paypal be screwing up the order notification?..
This happens when the customer doesn't return from Paypal, after they make the payment. It's not writing out the order..
Mine does the same thing, with paypal standard (business account)..
There are two contributions I see recommended frequently..
Shopping Cart (which allows you to get the information out of the shopping cart).
I'm sorry I don't know the exact names/locations of the contributions. If you search using those terms you'll find them..
I don't get that many orders, a day, so the simple solution was to put in "master login". I sign into the customers account and just check them out basically COD, so it doesn't take me back to Paypal. I just changed the COD text to "Office Use Only" and disable it when I'm not using it. Takes about 30 seconds. Not pretty, but simple, and does the trick for low volume shops..
There are many, many, discussions about this problem in this forum. If you do a search you should get the information you need to find a solution that fits your needs..
Sorry, can't be more help, but maybe that points you in the right direction...
Might want to check this out, as well..
I don't use the IPN and it's worked before, just now all of a sudden it doesn't seem to be working. I wonder if PayPal changed something?..
Like Billy said, if customers do not return to your Verisign site from paypal the order will not be recorded..
Checkout_process.php is executed after returning from paypal. If you don't want to use the ipn module you may want to try this one..
Order Logging Before Payment..
