New Post: the Cart is not empty, the order not cleared

Hello Rob,
I left there my morning post, but only in case someone will be in my same situation
actually everything now seem to work fine.

I felt something was wrong in a stage between paypal and the return back, and I realized I forgot to verify the credit card linked to the paypal account (the four digit code you need to find on paypal statement to verify your card).

Then I used again all browsers to buy and everything went smoothly.

So I think i can state that this could be the reason.

Sorry if i make you lose precious time...

again, thank you :)
