Security header is not valid

I am getting this message when trying to make the paypal module work:

 

Security header is not valid

 

I have tried to find a FAQ on this problem but can't seem to find anything. Where are such items located so I can read what to do?

First which paypal module are you trying to get to work and what country are you in?

 

Website Payments Pro and Express Checkout are only available in the USA and the UK last time I checked.

I installed Paypal Express Checkout and Payments Pro for the US.

I don't understand why people always answer questions by putting up a link when the answer can be so easy to just give. Links jump around, get deleted etc.... We need this information HERE ON THE PAGE when we need it.

 

The simple answer to this question is:

 

Note: If you use Website Payments Pro, you must implement both Direct Payment and Express Checkout.

 

That's all anyone had to say, right?

hi...i've been able to resolve that issue putting "live" on the transaction server, instead of "sandbox".

 

but now, in the checkout payment page, when i choose paypal, instead of going to the checkout confirmation to open the paypal page there, it opens the paypal page in the checkout payment when i click "continue"...

 

does anyone knows why??

 

i'm out of ideas...could it be some error in the code?

 

 

thanks :)
