Dear Prasun Sen,
I contacted service provider, they said all Ok from them. And then I tried deactivating all plugins and even changed themes. Nothing helped with that error
Then I installed woocommerce plugin and connected the course with woocommerce (as described (https://blog.calendarscripts.info/namaste-lms-bridge-for-woocommerce/). There the payment goes and is successfully redirected to the checkout page. But not to the course page and the student remained unenrolled.
Can you please provide some insight.
Thanks and Regards
Jai
