Thank you, however, if I understand correctly, I need a purchase code in order to post a support ticket there. I am trying out the free version for a customer, and who knows, maybe that will lead to a purchase of the premium version of the plugin, but if you insist that I have a purchase code in order to look into this problem then this support question will remain unresolved… I am happy to give you a login to the website if you want to take a look, but I will not be purchasing the plugin until I can convince my customer that the plugin works well.

Oh never mind, I found the database field em_mollie_api_key and emptied it, problem solved ??

Hi Patrick,
I am also getting this errorwith the 2.0.1 version:
Mollie\Api\Exceptions\ApiException thrown
Invalid API key: ‘sleutel-hier’. An API key must start with ‘test_’ or ‘live_’ and must be at least 30 characters long.
I had the problem first with the old version of the plugin. Then I updated to 2.0.1 and this temporarily solved the problem, I could access the plugin settings. I (rather stupidly) typed something in the API key field as a placeholder for my customer to paste their API key, but now I can’t get rid of it. Is there a database field that can be emptied? I have tried re-uploading the plugin via FTP but no success.
Any help is greatly appreciated.
Thanks!
Gary
