Paypal Express checkout issue Not installing correctly

[bps1418]

Hi,

I am unable to setup the paypal express checkout for my website wherein when I test the credentials it show me error message as "Security header is not valid." and if I directly run click on express checkout button from checkout page show me error message like "Paypal Express checout error".

Please suggest.
