    SetExpressCheckout API call failed.

    Error Code: 10002
    Error Severity Code: Error
    Short Error Message: Security error
    Detailed Error Message: Security header is not valid

    I do already use a plugin on my Webseite for Paypal standard, and on klick button and it works fine!

    Not I wonted to install the express button, but its just not working!
    I tred to put in my API informations, also to delete the chache and try it again!

    but it just giving me the same answer!

    Any Ideas what I can do?

    I know my API infos work!

    Is it maybe because I use https?
