10002 Security error - Security header is not valid

I, like others, am getting the:

We are sorry for the inconvenience. The PayPal account in this store is presently misconfigured to use mixed sandbox and live settings. We are unable to complete your transaction. Please notify the store owner so they can correct this problem. (10002) 10002 Security error - Security header is not valid

I had initially built my store using the full-fileset 12302006 version, then patched it with the latest ec patches. When I got this error, I thought it might be because I'd left out or misplaced a file in the patching process, so I downloaded the 1.3.7.1-full-patched-07052007 set and rebuilt my store from scratch. To no avail.

I am still getting the error. I logged in to developer.paypal.com, got my api credentials from the sandbox, copied and pasted, and ensured that there were no leading or trailing spaces in my id, password, or signature.

Anything else? I appreciate any help you can offer.

Thanks,

Patrick

That error message indicates that your API credentials aren't being accepted by PayPal.

Common causes:

1. You have your PayPal module configured to "Sandbox" but have not used Sandbox API credentials.

2. You have your PayPal module configured to "Live" but have not used Live API credentials.

3. You have mis-typed one or more API credentials entries, including but not limited to leaving trailing spaces.

4. You have deleted and/or recreated new API credentials in your PayPal account but have not copied those new credentials back to your store.

Thank you for your response, Dr. Byte.

Unfortunately, I've already ruled out all these errors.

However, it appears to be working for real in Live mode, so I am moving forward...

Thanks for adding that, Patrick. I was having the same problem and once I put it into live mode, it appears to be working also. :smile:

Glad to hear it, my store - http://straylight.tv/store is chugging along...

Mine too... now that the Payment mods are all working, I am sending out a mass email tonight! Waiting for the orders tomorrow. Every month I donate a portion of my sales to charity. http://www.customizthat.com


Good luck with your store!

Nice Job! Mine's so simple compared to yours!

LOL... yeah, I have close to 500 products right now and we are negotiating with another company... if the deal goes through, we'll be adding 23,000 products to our inventory.

I'm going to have to hire another person just to do all the cart operations. :cry:

LOL
