Troubleshoot common issues

Follow the steps in Troubleshoot common issuesarticle to ensure proper connection between Mollie and your WooCommerce instance and then the steps below for WooCommerce-specific settings.

Check Mollie webhook notifications

To trigger payment and order status updates, Mollie sends webhook notifications to the Mollie for WooCommerce plugin. These notifications are saved in WooCommerce so that you can check whether any webhooks have failed.

The WooCommerce logs contain Information on the success or failure of Mollie webhook calls.

If a webhook notification states that a webhook was unsuccessful, check whether payments are processing properly.

Get the log files

Mollie for WooCommerce keeps a log of all Mollie-related activity that takes place. You can use the log to investigate the root cause of a problem.

📘

Note

For Mollie diagnostic information to be available, you need to enable debugging for Mollie.

To get the WooCommerce log file, make sure you have the admin role and follow these steps:

  1. Go to WooCommerce > Status > Logs.
  2. Select a log file from the drop-down menu.
  3. Select View.

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

Important

Before updating Mollie for WooCommerce, review Mollie for WooCommerce releases to ensure compatibility with your version of WooCommerce or third-party plugins.

Solve common problems

Restore the connection

First, verify that you used the correct API keys.

If you have the Admin role, you can also perform the following tasks:

Ensure that external connections to https://api.mollie.com are not blocked by a site- or server firewall.

Ensure that SSL v3↗ is disabled on your server.

Ensure your server is up to date and that the latest security patches have been installed.

If applicable, ask the organization hosting your server to send a cURL request to port 443 on api.mollie.com via PHP.

Enable debugging
