MEC: 2.2.6 (The error documented below was present on an earlier version of MEC as well.)
Host: Media Temple
The entire reason that I purchased X theme for this website is because of the addition of Modern Events Calendar for making reservations and processing payment. PayPal Express works on my website and PayPal Credit Card does not. I’ve checked and MEC Documentation does not cover setup for any PayPal payment gateways. I am using MEC to allow customers to purchase a seat in a class. There is only one price/ticket available for each event. When I step through the workflow and attempt to process a credit card, an error message is displayed below the Pay Now button that reads “Payment is invalid.” No other information is displayed. I have tried using two different debit cards and one credit card and they all produce the same error. I have confirmed that I am using the correct API Username, API Password, and API Signature. I am processing payments in the Live environment.
Through PayPal, I have disabled blocking connections made from a server not using an SSL certificate. PayPal has been configured to accept API payments in My Selling Tools and the Business Setup has been configured to accept credit cards and PayPal on my website.
Please provide assistance with resolving the error message “Payment is invalid” and assist us with enabling the default functionality of the PayPal payment gateway. It would be a big help even knowing where log files are written so that I can locate the reason for the payment error.
