[PayPal Express] From Submission Error - [Security error] - Security header is not validAsked by tishaboo123 on September 15, 2014 at 03:35 PMok thank you,
So i was able to add the subscriptions and I tried testing the form and I
clicked the "Pay with Paypal" button and it didn't go through. It said that
the security header is not valid. Please help.
According to my research that the security header error means that there is something wrong with your paypal login information.
To resolve this please make try to re-enter information, when you are copying and pasting the login information please make sure that there are no spaces. It would be best to copy and paste the document to notepad before pasting it. One last thing is to check whether your paypal form is in sandbox mode, make sure you are not in sandbox mode.
