Cannot buy from store!

After I click at Check out it says "Welcome to the nginx!" (??)

What happens? Is buying currently disabled?

I very much doubt that. It is a server side fault, the same as the particularly perceptive "Broken" one when you post a reply.

In general, you click "Reload" on the browser, it then challenges you as to whether you wish to re-send the "form" material; so you say "yes". Whilst transaction systems warn of the risk of duplicating a transaction, if properly written they will not actually do so.
