Hello Prestashop Community.

First I would like tot hankyoua ll of you for making such a great shopping system.
It is without a doubt, second to none.

Now to my question:


Warning : the secure key is empty, check your payment account before validation


What is this?
I have setup the PayPal API details in Prestashop as it shows in my profile.
Running PrestaShop™ 1.4.0.17.

It has nothing to do with paypal api i think cause i use paypal but no api.

So if anyone knows if this can do any harm or to fix this message then please let me know.
