Troubleshooting

Whenever you experiencing some difficulties or troubles with the installation and/or configuration of the Mollie Payment extension for Magento® 2 you can check the following points to make sure the configuration is right.

1. Perform a API Check

Use the [Test API key] button to check if the API Key is valid. You can find the [Test API key] button in the configuration API Details section located in Stores » Configuration » Sales » Payment methods » Mollie.

2. Perform a Self Test

Use the [Run Self Test] button to check if your server meets the requirements. You can find the [Run Self Test] button in the configuration Debugging section located in in Stores » Configuration » Sales » Payment methods » Mollie.

3. Check if you enabled the payment methods in the Magento configuration of the extension

4. Check if you enabled the payment methods in your Mollie Dashboard

The payment methods are disabled by default in your account so you firstly need to activate the payment methods that you want to implement in your Mollie Dashboard.

5. Check if your currency is EURO

6. Check if the order amount min and/or max value is fulfilled

7. Check if there is any information in the logfile /var/log/mollie.log

8. Check if module output has been disabled

Located in the core_config_data tabel under path "advanced/modules_disable_ouput/Mollie_Payment". This ability to disable module output has been removed from the Magento Admin since Magento 2.2. If you disabled module output from the Magento Admin in a previous release, you manually need to remove this line from the core_config_table. If you have installed the module on Magento 2.2 or higher, please check the <Magento_install_dir>/app/etc/config.php file, see Magento DevDocs

Q: My logfile says "API Invalid", what to do?

A: Whenever your Logfile says "API Key Invalid" you need to double check if you copied and pasted the right API codes from your Mollie Dashboard. After you checked and changed this make sure that you flush your Caches as some settings are cached which results the same error in your logfile.

Q: Why is the Payment Status is Still "Open" After a Banktransfer payment?

A: In Magento® 2 the payment status "Pending_Payment" is invisible on the front-end by default. You can solve this by creating and assign a new payment status and set it to "visible".

Q: I'm unable to install mollie 2 module due to memory limit, what to do?

A: The required setting for installing and upgrading is 2GB RAM. Referring to the Magento DevDocs:

Magento 2.2.x technology stack requirements.

"Upgrading the Magento applications and extensions you obtain from Magento Marketplaces and other sources can require up to 2GB of RAM. If you are using a system with less than 2GB of RAM, we recommend you create a swap file; otherwise, your upgrade might fail."

If you are not able to get this changed manually, you can contact your hosting-provider to set these requirements.
