There should be more logs than that. Need to see the logs where 81002 is returned as a result from an attempt at SetExpressCheckout or GetExpressCheckoutDetails or DoExpressCheckout

That empty transaction is your problem.
I've never seen it do that before, not even in pre-alpha development stages.
My first guess is that you've got some missing or incomplete files on your server.
My second thought is that maybe since you're running v1.3.9e it might make sense to upgrade to v1.3.9h to fix all the bugs that were in the version you're using:

[4] => X-VPS-VIT-Integration-Version: 1.3.9e

Hi there, apart from updating zencart. How can I fix this....do I have to upload paypal again ??

[Didee]

Hi there, I have received this reply from Paypal support, but I have no idea how to do what they are asking.

The error message you are seeing:

[L_ERRORCODE0] => 81002
[L_SHORTMESSAGE0] => Unspecified Method
[L_LONGMESSAGE0] => Method Specified is not Supported

Is specific in its meaning and that is that either the Method value being passing in malformed/incorrect or that the it is not present. You will want to pull the API request that you are submitting and check the value of the Method sent to determine why it is incorrect. If no apparent after pulling this request please reply to this ticket with the request and I will test it further.

AND then this

You will need to contact support for your web editor/shopping cart to have them check the method than. The error referenced is returned by PayPal with the data sent from your card (specifically the variable METHOD) is incorrect. To determine the cause of the error they would need to log the data that they are sending to PayPal and adjust that field accordingly.

Can you instruct me as to where I may go to get help with this.thanks

Given that the upgrade from v1.3.9e to v1.3.9h simply involves replacing a bunch of files with updated versions, and since most of the PayPal-related files were involved in those updates, I would expect that taking that step may very well resolve the problem you're encountering.

Otherwise, you'll need to put on your programmer hat and study how all the Zen Cart payment handling systems work, how the PayPal API calls work, how the debug system works, and use that knowledge to figure out why the code is doing something very wrong when running on your server that it's not doing when running on thousands of other servers ... namely producing blank requests when submitting transactions to PayPal.
