Magento 2: Diagnose issues

You can use various sources of information to diagnose problems that you're experiencing.

Based on the information provided in these resources, you can determine a root cause for your problem to understand which troubleshooting steps to take.

All activity that takes place is logged by Magento 2. You can use the logs to diagnose the cause of a problem.

To get the log file, follow these steps:

  1. Log in to Magento 2.

  2. Go to Stores > Configuration.

  3. On the Configuration page, scroll to Mollie , select the arrow, and then General.

  4. Scroll down to Debug and logging, and click Check last 100 debug log records.

  5. View the log online, or download it as a text file.

The information provided in the logs should help you to understand which troubleshooting steps to take. We recommend that you share them with us whenever you contact support for assistance.

Check the release notes

You can refer to the Mollie for Magento 2 release notes↗ to check whether your problem was fixed in a newer version of the module.

Important

Before updating Mollie for Magento 2, check the Mollie for Magento 2 release notes↗ to see whether it works with your Magento 2 version. Otherwise, you might experience compatibility issues with Magento 2 or other third-party modules.

Check status updates

Mollie sends status updates to inform Magento 2 of the status of a payment or order.

Magento 2 also applies a status to orders, which are automatically mapped to a corresponding Mollie status.

Tip

You can customise the status mapping between Magento 2 and Mollie.

You can see both the Magento 2 and Mollie statuses for an order, to check whether they match.

Magento 2 only shows its own statuses. You can cross-check those with an order or payment status in your Mollie Dashboard to ensure that they're updating correctly in Magento 2.

  1. Check the Magento 2 order status.

  2. Check the Mollie status:

    1. Log in to your Mollie Dashboard.

    2. Go to Transactions > Payments.

    3. Search for the payment or order and check the status in the Status column.

  3. Compare the Magento 2 and Mollie statuses to ensure that they correspond.

If the statuses don't match, try the troubleshooting options listed in Payments not processing properly.

Check the API keys

Mollie connects to Magento 2 through API keys. A failed connection can result in issues, such as unprocessed payments, unavailable payment methods, or incorrect payment statuses.

You can check whether your API keys are correct in the module.

  1. Log in to Magento 2.

  2. Go to Stores > Configuration.

  3. On the Configuration page, scroll to Mollie , select the arrow, and then General.

  4. Click Test API key under API details.

If the API keys are incorrect, you can try to restore the connection.
