These are the tools our plugin gives you to troubleshoot a transaction.

Plans: Free / Professional / Premium Requires v1.0 Reviewed 12 November 2026

Start with the order notes

Open the order in WooCommerce and read the notes on the right. The plugin writes one for every step, and the note for a failed payment says who refused it and why.

The note says What it means
Payment declined by PowerTranz, with a reason The customer’s bank refused the card. The reason may be insufficient funds, an expired card or a wrong security code. The customer should try another card or call their bank.
The cardholder did not complete their bank’s verification step The customer closed or failed the 3-D Secure step. Nothing was charged.
The store is configured to decline unauthenticated payments The card does not support 3-D Secure and your setting is to decline those. See 3-D Secure.
The fraud check declined this transaction Kount refused it. See fraud screening.
The payment session expired The customer took longer than five minutes. Nothing was charged. They can try again.
PowerTranz rejected the payment request A setup problem, not a card problem. The note often names it, such as the hosted page not being found or the merchant not being recognised.
ACTION REQUIRED The result is not known yet. See interrupted payments.

What the customer was told

The customer sees a short message at checkout, such as being asked to try another card, and never sees technical codes.

Turn on the debug log

  1. In the gateway settings, under Advanced, tick Debug log and save.
  2. Repeat the payment.
  3. Go to WooCommerce, then Status, then Logs and open the newest log named wpc-powertranz.

Card numbers and passwords are removed before anything is written, so the log is safe to share. Turn the log off again when you are done.

What to send us

  • What you did and what happened.
  • The text of the order notes.
  • The debug log for that payment.
  • Your WordPress, WooCommerce and PHP versions, from Tools, then Site Health, then Info.

Never send us a full card number or your PowerTranz password.
