Supportform - mollie/mollie-oxid GitHub Wiki
In the overview tag of the plugin settins, you are able to contact the Mollie support directly.
This is the preferred method to contact the Mollie support, since a log file. This log file will contain the API call (request and response) of the last seven days, but max. 700 entries, and will be attached to the e-mail sent to the Mollie support.
For reference, you will get a copy of the sent e-mail.
