In this version we added new shortcode functionality which allows to place payment form for any particular service, either by service ID or by service name. To update the script simply go to your wp-content/plugins folder and rename (or remove) paypal_payment_terminal folder, then re-download distributive from codecanyon and upload to the same folder wp-content/plugins with the same name "paypal_payment_terminal". That’s it!

Now you can use following shortcodes:
[pppt_paypalform]
[pppt_paypalform sid="service-id"]
[pppt_paypalform sid="service-name"]


Not to confuse, 2.1 is the version of the script, it works with wordpress 3.0 and above.
