Paymill - Common Payment Gateway API - not showing

I am trying to setup PayMill with Hikashop. (I could use any other inexpensive payment gateway provided it accepts major credit cards and bancontact and/or Maestro)

There are two solutions:
the PayMill plugin for hikashop - failing with php error on line 206 when activating it in the last step of the purchase process
the common payment gateway plugin for paymill, successfully installed. This one requires the Hikashop Common Joomla Payment API integration, installes and configured.

When I try to define a payment method in Hikashop, this plugin is not even in the list!!!

Any suggestion about integrating PayMill with Hikashop or on another inexpensive payment gateway working reliably with Hikashop.

Thanks a lot!

Well well well,

Thank you for your prompt reply. The process you describe is precisely the one that isa failing.
1) I have the plugin ready in joomla (see list in attached hka1 print capture)
2) it is not present in Hikashop (System->Payments->New) (see the 3 remaining screen captures)

Is there a way to fix this?

I have another strange behaviour: the PayMill plugin I installed by mistake (incomplete doc - i found later that it was not working with Joomla 3) is still present in the list even after I removed it form both Hikashop and Joomla. I'd be glad to know the way to manually remove it.

Thanks a lot

Besr regards,
Serge

Hi again,

Next step, I completely removed the plugins and files.
I downloaded the latest version of the paymill plugin ( github.com/techjoomla/joomla-payments/tr...code/plugins/paymill ) and installed it.
Configuration in two steps:
- within Joomla, providing only both private and public keys for test mode;
- within Hikashop, The Paymill plugin is back in the list. I configure it by giving it a name, bank card images, API keys again (the same) , and test mode. It shows that this plugin is a commpon payment API (finally).

When I test it, during the checkout operation, I got the message
Fatal error: Call to a member function get() on null in /home/XXcensoredXX/public_html/plugins/payment/paymill/paymill.php on line 82. This line is trying to get the api keys. It seems that, one way or another, the communication between Hikashop and the Joomla payment plugin is failing.

Any clue ?

Thanks in advance,
Serge
