wordpress memberpres stripe payment gateway error in processing

My Memberpress stripe integration is not working. I keep getting the following error message whenever I test a credit card transaction via stripe.

ERROR: There was a problem sending your credit card details to the processor. Please try again later. 1 Array ( [action] => checkout [txn] => e [mepr_process_payment_form] => Y [mepr_transaction_id] => 14 [mepr-cc-type] => )

Can anyone provide solution? Thanks in advance.
