Any help would be appreciated. The Paypal express worked at first and was GOLD.

Thanks in advance.

(sandbox transaction)

You've got the module set to Sandbox mode, but you're probably using a live account.

If you're using sandbox mode, you need to get sandbox API credentials.
If you're using live mode, you need to use your real account API credentials.

That was the first time I tried sandbox mode.

I'll try real account.

Why wont my SSL work?
