Payment methods not available for Subscription Plan

-- HikaShop version -- : 3.4.0
-- HikaSerial version -- : 2.1.1
-- Joomla version -- : 3.8.7
-- PHP version -- : 7.1

Hi Guys & Girls,

I have just bought and setup HikaSubscription.

I have made my first plan and associated it with a product. However, my payment methods cannot be found for that product. It says, "No payment methods found". Payment methods for all non-subscription products are functioning.

How can I get the payment methods to work for HikaSubscription?

See attached for your reference. Please assist promptly. Thank you.

Hi Jerome,

Hi Jerome,

Which code do I use? All the code or a code from a specific post?

Please clarify. Thank you.
