Magento, a popular e-commerce platform owned by Adobe, offers two software versions: the original Magento 1 and the feature-rich Magento 2. Effective June 1, 2020, Adobe stopped providing technical support for Magento 1, halting the release of security patches and functional updates for the older version.
Mollie has a Magento 1 module and a Magento 2 module. We recommend that you switch to Magento 2 and install Mollie for Magento 2.
If you use Mollie for Magento 1:
Make sure that you are using the latest stable version (Magento 220.127.116.11.) for secure operation.
