<p>IPN ERROR :: No saved Website Payments Standard session data available. Must be an Express Checkout or Direct Pay transaction.
Could be a test notification, or the incoming IPN notification is not actually a bonafide PayPal transaction.
NOTE: It is likely that all the following log content is meaningless or irrelevant.</p>

I'm trying to find out if these are legit transactions or some kind of test they are doing to make fraudulent purchases, or an error in the plugin ... :no:

Because these debug log was way too long and it kept repeating the same steps 2 or 3 more time, and then finally it displayed the last part, but not transaction, no sale ...
So that keeps me wondering if this was a hacking attempt, or an error in the plugin or the configuration????

Really not sure why this is happening ...

but the domain is from an authorized country ... Germany
