WooCommerce: Solve common problems

Solve common problems that may arise, such as those caused by inactive payment methods in your Mollie account.

Restore the connection

Mollie ensures a secure connection to WooCommerce using API keys. Incorrect API keys can cause unprocessed payments, payment methods unavailability, or incorrect payment statuses.

To verify that the API keys are correct, follow the steps given in Connect to Mollie.

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 organisation hosting your server to send a cURL request to port 443 on api.mollie.com via PHP.

Activate payment methods

If a payment method is inactive, or was deactivated in your Mollie Dashboard after you added it to your checkout, it may not appear in WooCommerce or your customer may get errors when trying to pay.

Ensure your chosen payment methods work flawlessly with your e-commerce platform by managing their activation status in your Mollie Dashboard.

To activate payment methods in your Mollie account, follow these steps:

  1. Log in to your Mollie Dashboard.

  2. Go to Settings > Website profiles.

  3. Click Payment methods under the website profile.

  4. Use the toggles to activate your payment methods.

    A blue toggle indicates that the payment method is active. A yellow toggle indicates that it's pending Mollie's approval.

    Important

    Some payment methods require Mollie's approval before they're available in your Mollie Dashboard. If your account has been approved but payment methods are still missing from your dashboard, contact support.

Enable debugging

Enable debugging for comprehensive log files that provide detailed insight when troubleshooting issues.

Note

Enabling debugging increases server storage requirements due to additional log data.

  1. Log in to WooCommerce.

  2. Go to WooCommerce > Settings.

  3. Select the Mollie Settings tab.

  4. Scroll down to Debug log and select the checkbox.

  5. Save the changes.

Reactivate the plugin

In some cases, it helps to deactivate and reactivate the plugin. This resets the plugin without losing your configuration settings.

  1. Log in to WooCommerce.

  2. Click My Sites

  3. Click the name of the relevant network site.

  4. Click Plugins.

  5. Scroll down to Mollie for WooCommerce and click Deactivate.

  6. Click Reactivate.

Reinstall the plugin

In some cases, the best option is to uninstall and reinstall the plugin.

Note

By default, Mollie configuration data will be retained when you uninstall and reinstall. If you want a complete uninstall, select Remove Mollie data from Database on uninstall in the advanced settings of the Mollie configuration page.
