I have an EE 2.7.3 site running CartThrob Pro 2.5. The site is running on a Nexcess server and we have SSL installed. We set up the gateway values for Paypal Website Payments Pro, and I have tested against the following:
- sandbox with paypal sandbox testing credit card
- live mode with actual paypal values and two different "real" credit cards
In all instances, we are getting the following error: "Declined: Timeout processing request"
I have verified that cURL is enabled. I also tested with the sample cart templates provided by CartThrob. We always get the same error.
Does anyone have advice on what to check or how to troubleshoot this one?
