Hi everyone, I have recently installed Paypal Express from my cart. When I went to do a test buy using the Paypal express button, I get this error:

Security header is not valid. It does it in both the sandbox and live. Could someone help me or direct me to a page for this? Many thanks!

This topic has come up a few times in the past, have you tried a search of the forum for an answer?

Yes, but did not find the needed answer so posted here.

I had this error yesterday and had to search for ages (searching doesn't always get you the answer from oscommerce...I ended up on google and found it on a zencart forum!)

If you have the same issue I did you may be using the incorrect credentials - eg. if you are in sandbox you need to get sandbox api credentials, if you are in live you need to get the correct api credendtials from your profile in paypal...

I hadnt realised the sandbox worked off completely different info to live and it wasn't working for me...I can now proceed in box live and sandbox

if that isn't correct, maybe post up how you've got the module configured in your admin panel so I can compare? I am new to osc though so can't promise too much
